Question

Check whether the given numbers are divisible by 7 or not :- 427,3514,861,4676

Answer 1

As we know that divisibility rule of 7 is that the If the sum of the digits is divisible by 7, the number is divisible by 7.
So, 427
4+2+7=13
427 is not divisible

3514
3+5+1+4=13
Not divisible

861
8+6+1=15
not divisible

4676
4+6+7+6=23
Not divisible

Answer 2

Hello mate !
Divisibility of 7 is remove the last digit,double it,subtract from the truncated original number and continue doing it until only 1 digit is left If it is 0 or 7 number is divisible by 7.

● 427 = 2(7) = 49, 49-42 = 7
Hence it is divisible
● 3514 = 2(4) = 16, 351-16 = 335
Hence it is divisible by 7
● 861 = 2(1) = 2, 86-2 = 84
Hence it is divisible by 7
● 4676 = 2(6) = 36, 467-36= 431
Hence it is divisible by 7
Hope it helps you ✌ ✌
