Thank you sir you always tell best tricks and shortcuts, but I have a doubt that how we will check whether a number (big number) is itself a prime number or is product of prime numbers?
Fantabulous sir! I was confused of such a large number in factorisation method but u really explained those doubts properly with a easy method... Thank you sir.
Finally found this type of video Bcoz in other videos people do prime factorisation in which numbers are even on last But sir u noted that point and maked a video which is very helpful for me and others thank u so much ❤❤❤
You should include skills required for each video, under the description. Like in this video - Vedic multiplication, divisibility rule for first few primes, primes under 100, squares upto 25 and so on.
Hi! Great method! I was wondering about specifically 289 and its factors. Is this one that you have to memorize as 17*17? For numbers ending in 9, are you ever needed to check __7 * __7? Thanks.
It ends in 0, so we have a ten. The digits do not add to a multiple of 3. Since 1001 is 7*11*13 we can quickly look at the next three. 79570 - 70070 is 9500. 95 is not divisible by 7. Nor 11, nor 13. Next up is 17. 7957-17 = 7940. 794-34 = 760. Not 17. His method has us look at that last 7. And has us looking at factors that can multiple to 7: 3x9 or 1x7. I didn't want to listen to all 13 minutes of the video. I used Google. If you check all the primes (yeah, ending in 1,3,7, or 9 includes all of them) upto the square root of 7957 (89) you will discover 73. 79570 = 2 x 3 x 73 x 109.

Thank you very much. I was struggling a lot with this. Now just a bit of practice can help.
Ha bhai Bgmi aaoge? 😌
I'd?
Me also
10:39 51 is still divisible by 3 as well as 17.
Yeah it was my confusion too
Yes and the last number 2279 he forget the 3th possibility of digits multiplication ~> ___7×___7 whethewer at the final 43×53 war the correct answer.
Lot of thanks sir. It is rare in youtube

Jisko jisko samajh me aagya wo v phli baar me like here so that i can know how intelligent u r
thank you, it really helped me
Thank you so much sir it's clear my doubt about prime factorise
Thank you sir , this trick helped me for quick calculation since m preparing for jee this is actually a saviour 👍
10:35 51×23= 1173 ,thank me later sir 😅
Wat if the factors are more than 4
THANK YOU SO MUCH SIR THIS WILL HELP ME IN MY TEST TOMORROW
THANK YOU SIR ONCE AGAIN😊😊😊😊❤❤❤❤
Thankyou sir. It was very helpful!
Thankyou so much sir! I was struggling with prime numbers You made it really easy 🙏
Your smile is good😊😊
Thank you sir... You helped me a ton and I became a topper... :)

Thank you very much sir,,
excellent sir ....im grateful
Awesome explanation
Thanks very helpful :)
Loved Your Video sir. It Saved My time thanks for such an amazing videos🥰
Thank you very much. Quite a bit of trial and error but facinating.
In problem 4, you didn't have to try 51 and 23 because 51 is not prime. Knowing that would save time
Ha bhai tum padha doh 😂
Listen, beginners can also watch this video & u must fix ur grammar bcaz udk where to use didn't and did not
With list of prime numbers in memory, this trick will significantly help in faster calculation. Thank you.🙏
5:44
There is another possibility 9×9
Awsome Explaination!
Please sir make a video in hindi of same topic
Thank you for this sir! 😁😀😀
Tq so much sir
Awesome!
You explained very nice but try if you can go a little faster
Sir what is the prime factorisation for the number 123456789 ,please reply sir ,doing prime factorisation for such a large number?????
This large number is divisible by 3² etcétera
thanku sooo much sir 🙏
Nice explanation Sir, watching from Germany!! Wish you good luck!!
Do share it in your amazing country 😍😍
what if the number has more than two prime factors?
Thanks sir ❤️❤️
If a factor is ending by 0 then?
5 and 2
0 last me rahega to wo even number hena 2 se devide ho jayega
Sir thank you very very much for this awesome trick, this trick can help me in solving my complex questions. Once again thank you very much Sir 😊♥
Thankyou so much sir ....😇
Thanks
Thank you keep it up👍
Sir please tell me P. F method of 20677 and 🙏 reply🤔
thank you sir for teaching us
In the last sum it also end with 7.7
Thank you so very very very much
thnku very much sir
4th bit 1073
We can do with 52×23
52 is not a prime number
Thank you sir ❤️
Thanks for this trick 🙏 it is veryuseful 🥰
Your maths tricks are very nice
Tysm i npw understand -miguel
What if there is 0 in the units place ? Ex: 4180 ? How do we proceed then ?
Divide by 2, divide by 5... Then you'll have a smaller number...
Yes it is clear that is will be divided by 2 or 5
Then you don't even need to do all these steps just divide by 2 or 5 xD
2 se divide ➗️ karo
In case of ,391 we could consider as the form __9×__9
9 is not prime
Can you calculate for 551?? By this method
Yes you abously right
Keep it up 👍👍
Dude 9 is not prime
29×19 =551
Video start from 2:43
In question 2 one more possibility is 9×9 sir ,isn't it?
9 is not a prime no.
9is not pn
@@neelamneelam4013 yet 19 is a prime...if we were to factorise 361 then only 19 * 19 will work out...
is the answer of 9x1089 or 1089x9 that also would end in a 1 the number reversed backwards from the number 1089 itself?
What if number is product of more than 2 primes
Very nice sir
lyyy mannnn u saved me
Sir please do 105840 for me sir. Thank you
13*5*3*2^7
Brother I will help
2*2*2*2*5*3*21*21
Thank you very much
Here ve take 11× 3 also in 143
Let me try now
Me apne no. Ke prime factors nikalne ki quick tip dhundne aaya tha aur ish video me mere wo 2 no. Pehle se hi ha 391,527
No. Of adds are a lot .that's only problem otherwise good explanation😊
Thank you for this trick sir👍 very helpful 😊
Hiiii sir
Hello
I want prime factarizetoin 5620 on this number sir
what are the prime factors of 1001 sir ??
7×13×11
Yeah how did you find those could you please elaborate
Bro always go for the number from the end
It's last digit is 1
So it can divide with 11,1,7,9and 3
It helped a lor
Thank you sir.....👌👌👌👌👍👍
One video in fully RUclips
Thank you sir 🤗🤗🤗🤗
This video help me so much
But little bit difficult
Please tell what to do when you have an even number?
Wow. Divide by 2. And then check for 2. And then 3....
Thank u sir
Why last one not ending with 7 both?
great
Nice...👌👌👌
Sir please solve 5005 on this method 😭.and send me reply
It is 5×1001 which is 91×11×5
Remember 1001 factors then you can easily find out 6006,7007,8008,... factors
5005 = 5×7×11×13
thanks bro ask the good question and good answers came dis qs
Class 10 ha ?

Sir plz make this vedio in hindi language
WHY DO YPU LOOK LIKE THE MATH TEACHER OF ISHAAN IN LIKE STARS ON EARTH????
But your examples are of multiples of only two prime no what if questions come from products of 3-4 prime no
Sir please do the prime factorization for cube number like 79570 if it is a cube or not
It ends in 0, so we have a ten. The digits do not add to a multiple of 3. Since 1001 is 7*11*13 we can quickly look at the next three. 79570 - 70070 is 9500. 95 is not divisible by 7. Nor 11, nor 13.
Next up is 17. 7957-17 = 7940. 794-34 = 760. Not 17.
His method has us look at that last 7. And has us looking at factors that can multiple to 7: 3x9 or 1x7.
