Question

find the divisibility rule of 4,8,11​

Answer 1

Divisibility rule for-

4: last 2 digits of the number should be divisible by 4.

Example- 6620, last 2 digits(20) is divisible by 4 ∴ 6620 is divisible by 4

8: last 3 digits of the number should be divisible by 8

Example- 81024, last 3 digits (024) is divisible by 8 ∴81024 is divisible by 8

11: the difference of sum of digits at odd places and even places should either be 0 or divisible by 11.

Example- 13321, sum of digits at odd places= 1+3+1=5

sum of digits at even places=3+2=5

Difference b/w them= 5-5=0. ∴13321 is divisible by 11
