Any number is divisible by 5 if it has 0 or 5 at unit place.

  • All the multiples of 5 end in either 0 or 5( alternatively). For example:

5×1= 5, 5×2=10, 5×3 = 15, and so on.

  • Similarly, multiples of 2 end in an even number.

Example: 2,4,6,8,10, 12, and so on.

  • Similarly, for a number to be divisible by 3, the sum of all the digits should be divisible by 3.  

For example: 85203

The sum of all the digits is 18 which is divisible by 3.

  • In this way, we have divisibility rule for most of the numbers.
