                         Divisibility Rules   Divisibility by 1  Every number is divisible by 1. It does not have any condition. Any number divided by 1 will give the number itself.  For example, 8 is divisible by 1 than answer will be 8 and 6789  is also divisible by 1 than answer will be 6789.  Divisibility by 2   If a number is even or a number whose last digit is an even number i.e.  2,4,6,8 including 0, it is always completely divisible by 2. For example -   Let's take 216  it is an even number so it will be divisible by 2 completely. If we take 765 it is not an even number so it will not be divisible by 2.  Divisibilty by 3  Condition of Divisibility rule for 3 is a number is completely divisible by 3 if the sum of its digits is divisible by 3. For example-  let's take a number 723 add the digits  7+2+3 = 12 , after adding the digits we will get 12 it is a multiple of 3 so the number 723 is divisible by 3 .  Let's take another number 562 add the digits 5+6
