Every number is not completely divisible by every other number such number leaves a remainder other than zero. A number is said to be divisible by 8 if the remainder is 0 and a quotient is a whole number. If it is completely divisible then we call it Exact Divisibility. The multiples of 8 will be the even numbers. There are certain rules to check the divisibility test by 8 for larger and smaller numbers.

The test of divisibility is used for simple and fast calculations in divisions. This divisibility rule helps you to check if the number is completely divisible by another number without using the division method.
