I am WILLING to be on my knees for you oh my lord. Thank you so much for the shortcut! At first I thought it’d be the normal tree or table method but it was a trick we could do mentally and quick once we’ve developed a habit. Subscribed to your channel ❤
My pleasure 😊 thank you so much for your kind appreciation 🥰
o bas kia kr yara bsdk
@prahor9894his mom prolly had him on gun point 💀 so this trick may helped him WAY TOO MUCH ☠️
Could really relate brother
Same to same
Hi, I am putting a question here related to this topic. You guys can use the trick given in the video to solve this and put your answers in the comment section! I will let you know if your answers are correct or not!
The question is:
Find LCM of 24, 36 and 12
LCM of 24, 36, and 12 is :- 72
Mam is the answer correct...?☝️
Mam, answer is 72
Answer is: 72 mam
LCM =72

oh my god i was on you tube for 3 hr and found this video and now I know how do do it god bless u
Thank you so much for your kind appreciation ❤️
Anyone in 2024
Hey I am there tomorrow is exam 😅😅
I also
Me
Iam
Im still struggling with lcm and I'm in 8th grade 😭😭
Thanks madam.. Best teacher I have ever met on social media.🥰
My pleasure 😊
@@FastandEasyMaths 🥰
That’s a fact brother.
@@FastandEasyMaths it was very easy after watching this video
That's a fact aye
Best technique I ever practiced....
Thank you mam
My pleasure :)
Thank you, as a G5 student,
this is our topic, and an upcoming exam, i have a hard time understanding this Lcm and Gcf, this really gonna help me, thank you so much.... i hope you can help more people having a hard time... 😁😄😀
My pleasure 😊 kindly share it with your classmates too ☺️
@@FastandEasyMaths Sure! by the way, do you have a vid link of. finding GCF? thank you😄
Hey, thank you for the video. Could you help me in solving these questions?
1. Find the LCM for 3,18,21
2. Find the LCM for 9,13,26
I can't get it by doing your shortcut method. If possible do a video on this. It would be extremely helpful for me.
For the first one largest number is 21 and when you multiply it with six you get 126 which is divisible by 18 and 3
For the second one largest is 26 and since nothing is common between 9 and 26 your LCM will be 26 × 9 = 234
Hey I got it. Thanks a million
I’ve got 40 and 56 and have to find LCM. How would I work it out

Very informative ... keep the good work on ...
Thank you :)
Mam jus 2 questions.
If we need to find lcm of 3 different numbers like 4,5,6? then what's the rule?
Question 2) if there are 2 prime numbers in a question what's the rule, like 2,4,5,7,12?
Thank you
This method has saved a lot of time
Thank you so much ❤
My pleasure 😊 kindly share this with your friends too 🙂
Thank you for helping me i have js entered high school and hv a test to do u helped me alot❤,can u do a video of multiplying fractions please?
I am very weak in that area and in division
ruclips.net/video/M0l_-MPm5_c/видео.html
This is the video to understand how to Multiply fractions
Any one 2050 😂
1)What if, the largest number is not divided by other two numbers in series...?
2)What if, the set contain two prime numbers?
i remember using a slightly differenct variant of this method. i discovered it myself:
lets say i have a set of numbers, and i have to find the lcm of them
set of numbers: 1, 3, 12, 15.
The method i use is slightly faster here.
1. Here, i notice that there is a trio of numbers that are multiples of three (3, 12, and 15)
2. i take the largest number (15) and divide it by the smallest number (3) to get 5.
3. i look at the remaining set of numbers to check for any pairs (there aren't any in this case, so i proceed onto the next step. If there were, i'd do the second step).
4. In this case, there are no more "pairs", so I proceed. There is only another number in the list which is 1, but that doesn't matter since every number has 1 as a factor. I multiply my result of 5 (15/3 done earlier) by the remaining number (12) to get my LCM: 60.
Now let's apply that to the lists done in this video:
list: 4, 8, 16
1. I notice that there's another trio here, consisting of multiples of 4
2. I take the highest number of the trio (16) and divide it by the lowest number in the trio (4) to get 4.
3. We then divide the remaining number in the trio (8) by the result (4) to get 2.
4. 2*8 is 16, which is the LCM. in this video, the strategy you used is faster than mine, as the example used is a simple one.
Onto the next one:
list: 3, 4, 6, 18
1. We take all numbers that are divisable by 3 and put them in a trio. In this case, we take the largest one, as it has all the divisors of the other numbers in the list (18). We now have 18 and 4
2. we notice that both are divisable by 2, so we divide 1 of them by 2. 18/2=9
3. 9*4 =36, which is our LCM
the third example in the video:
list: 5, 10, 15, 20
1. we notice in the list that the 20 has both 5 and 10 as factors, so we are left with 15 and 20.
2. we notice that both are divisable by 5 (15/5=3; 20/5=4), so we divide 5 by preferrably the largest one (20) by 5. 20/5=4
3. do 4*15, which gives you the lcm of 60.
its a hard strategy to understand, but once you get the hang of it, you can go real fast,
Bit longer
Useful thought for my understanding...thank you
can we use this trick for every problem. is it works
👏
I really appreciate how you replied all comments
Thank you 😊
Before I think math is very hard but after this video! I don't think this! 😍thank you
My pleasure 😊
😊😊😊😊😊😊🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉😢😢🎉
🎉🎉🎉
This was very helpful
Thank you so much I needed this 😊🙏🏼🙏🏼
Amazing video but I have a question what if there are multiple prime numbers would you times it by the highest?
Only if the highest isn't divided by any of the prime numbers, for ex if you have 2, 3, 15 then your LCM will be 15× 2 since 15 is divided by 3 so 3 won't be taken into consideration for the LCM,
If the numbers are 2,3,25 then in that case you multiply 25×2×3 to get your LCM

Nhi pategi bhai🙂
thank you so much didi ,dimag ka dahi ho gaya tha kasam se,har koi falto dekha raha tha lekin aap pahele jo achachA bata rahe ho carry on.....
Greetings!! I would appreciate it if you could explain me how to calculate the LCM of 24, 36, 44 and 62 using your technique.
Dear Mam,
Can u apply your lcm trick on this 48, 64, 90, 120 ?
Yes
TLDW: LCM: Take the highest number, check is it a multiple of the other number/s. If it is, the LCM is the highest number.
Non multiple method: Find the highest number, check is it a multiple of the other number/s, if not, multiply the highest number by 2, then check is multipled number a multiple of the other number/s. If it is, the LCM is the multiplied number. If still doesn’t work: cancel out the multiplication, and multiply the highest number by 3 then check is it a multiple of the other number/s, then the LCM is the multiplied number (x3 num). If all my methods don’t work (prime num problem) and the highest number can’t be a multiple of a number/s, you need to multiply the highest number by the prime number. Then the LCM is that multiplied number.
thanks for the amazing video
How do you solve LCM if there are two prime numbers, using your LCM method?
Oh mighty and magnificent Least Common Multiple (LCM), I bow before your mathematical prowess! Your ability to unite the numbers of the world in perfect harmony transcends all boundaries, and for that, I offer an eternal debt of gratitude. This time you made it easy. THANK YOU!
It's my pleasure 😊
If it's 3,4,5, we'll have to go all the way to 5*12, is there a shortcut for such numbers, would take a lot of time here too, better to go traditional when numbers are small right?
No here, when you have highest number as 5 and the other number is 3 which is prime so you can directly multiply 3×5 and the left over number is 4, so you can then multiply 3× 4× 5
Hello ma'am, can you please make a video on rational and irrational numbers please? I loved all your other videos. Thank you for your efforts ❤️🙏
🎉
I have doubt doubt is
If A = 2x²+4y²-2xy
B = 2x²+14y²-2xy
C = 3x²-2xy+2y²
D = 4x²-16xy-2y²
Find 2A+3B-C-C
that took WAY longer than five seconds.
😂
Same
😂😂😂😂😂
It doesn’t really matter at least it’s faster than the other method!
@@misraktolossa3021 lol I guess🙂

THANK YOU VERY MUCH IT HELPS ❤️❤️!!!!
My pleasure
I like this video 🎉🎉🎉🎉🎉🎉🎉🎉🎉🎉😊😊 what is very useful for me it is very very easy method thank you
So sweet I like the fastest method .. thanks for sharing
Will this LCM method work on every prime number and numbers with more numerical values
Yes
Yes
If there was a set of numbers, and two of the numbers in the set were not divisible what would you do? For example, 2,3,7,11,12. There are two numbers which are prime numbers. How do I solve that?
You multiply all the prime numbers together that are not divisible. In this case you have 7 and 11, so the LCM is 7 x 11 × 12 = 924
Madam you are solve my problem 😍❤️ thankyou so much

Mam using the trick how to solve Lcm for 8,12,16
Out of three 16 is highest so you try 16× 2 = 32 that doesn't go in 12 so you try 16 × 3 = 48 that wil go in every number so LCM is 48
🎉Thank you so much mam

Thank you so much kaki
If hcf is not multiple by any number what we should do
Thank you so much madam l learnt in 5minutes
My pleasure 😊
what happens if we need to find lcm where multiple prime numbers are present: ex: 7,13,23 and 37
multiply all of them.
or just multiply the biggest prime number
