Trick 103 - Check Divisibility by 13 and 17 in 10 Seconds

Sometimes making prime factors seems difficult because we are not aware of the divisibility rules of large numbers like 13, 17, 19 and so on....in this video I seek to explain an easy method for checking whether a number is divisible by 13 and 17 or not.....For more such amazing shortcuts....keep visiting:

Sir, It was an amazing method, I am interested in knowing more shortcuts to tell my students in interior region of mountains where people don't have much facility. I also want to know that, is there any rule to put 0 before any division is started... Example 55/5=011please do reply

Sir please reply about 0 to be put before quotient...

very nice concept sir

Sir can I take tuitions from you?

[@raviteja-so2jn]

Sir 13 power 17 -1 dividable by 12 and 14 . Tell us sir

[@jyothineeluri6278]

Good shortcut method

[@gigimc230]

Thanq ......great work sir

[@arith04]

Great video

[@pksgkri]

If the number is large then these methods are quite laborious. Then it is better to perform division and find divisibility

@@sureshaggarwal Hi sir ! This is great method. I have also found a way to make trick for divisibility test of all natural numbers in just few seconds ...
For example divisibility test of 23 is multiply unit digit by 7 and add the rest number ... Like wise I can find the divisibility test of a number divisible by 353 in just few seconds .

[@pranavpudke5318]

good one

[@pksgkri]

Request to our learned teacher to impress on all children to memorise muliplication tables from 1 to 20. Then some steps can be avoided.

gazab sir ji maja aa gaya

[@dt3042]

Sir could u explain why it works?

[@Fete_Fatale]

proof that 13 is a multiple of 13
13 ... {1}:{3}
1 + (3*4) = 1 + 12 = 13 ... using this rule
13 = 10+3 ... simple addition
10/10 = 1 = 10-9 ... dividing 10n by 10 is the same as subtracting 9n
10 - (3*3) =1 ... subtracting 9n is the same as subtracting 3n*3
13 = 10+3 = [(10/10)+9]+3 ... (10/10)+(3+9) = 13 ... and since 3+9 = 3*4 then ... (10/10)+(3*4)=13
Try it with these ...
26 ... {2}:{6}
2 + (6*4) = 2 + 24 = 26 = 13*2
39 ... {3}:{9}
3 + (9*4) = 3 + 36 = 39 = 13*3

[@vandanaahuja6414]

too good........nice

[@muraris4735]

13*14=182:but 2*2=4 on adding 18+4=22 ?

[@kncethater127]

Bro u r wrong bro check the multiplication crctly

[@vanshikajain6669]

2×4=8
18+8=26
26 id divisible by 13
So 182 is divisible by 13

[@nileshkumar6623]

Sir for 11069 how i chake the divisibility by 17

[@avinashrockooo]

Thank you sir 🙏

[@bindusaini362]

Excuse me sir
The letters on board r too small
Not visible easily

[@sourabhsolanki2385]

Sir last main zero Raha toh

[@speedstar6140]

Then also it is divisible by 17, compare it with divisibility test for 11 where when we subtract the sum of digit at even and odd places, then if the no. Obtained is a factor of 11 or simply zero then that no. Is divisible by 11
