Divisibility rules of numbers

Divisibility rules-

1. Divisibility rule of 2 -A number whose unit place is divisible by 2 (unit place 0,2,4_6,8) then the number will be divisible by 2.Ex-124, here unit place '4' is divisible by 2 then 124 is also divisible by 2.

2. Divisibility rule of 4 - A number whose last two digits(number formed by unit place and ten place) is divisible by 4 then the number will be divisible by 4.Ex-432, here last two digits '32' is divisible by 4 then 432 is also divisible by 4.

3.Divisibility rule of 8-A number whose last three digits (number formed by unit place, ten place, and hundred place) is divisible by 8 then the number is also divisible by 8.     Ex-3456, here last three digits 456 is divisible by 8 then 3456 is also divisible by 8.

Note:- 2= 2¹→last one digit.

           4=2²→last two digits.

           8=2³→last three digits.
