## TESTS OF DIVISIBILITY

A number is divisible by 2 if its last digit is divisible by 2 or its last number is 0,2,4,6,8.
For example:5623786 is divisible by 2 as 6 is divisible by 2

A number is divisible by 3 if the sum of digits is divisible by 3.
For example:1776 is divisible by 3 as 1+7+7+6=21 is divisible by 3.

A number is divisible by if the number formed by last 2 digits is divisible by 4
For example:6476536 is divisible by 4 as 36 is divisible by 4.

A number is divisible by 5 if its last digit is 5 or 0.
For example:68470 is divisible by 5 as 0 is its large number.

A number is divisible by if the number is divisible by 2 and 3.
For example:300 is divisible by 6 as 300 is divisible by 2 and 3.

A number is divisible by if the sum of digits is divisible by 9.
For example:8811 is divisible by 9 as 8+8+1+1=18 is divisible by 9.

A number is divisible by 10 if its last digit is 0.
For example:1748650 is divisible by 2 as 0 is its last digit.

(the process of test divisibility of 3 and 9 is same)
