A divisibility rule is a shorthand and useful way of determining whether a given integer is divisible by a fixed divisor without performing the division. One can simply divide the number by 2 and then check the result to find it is divisible by 2. If it is, the original number is divisible by 4. The divisibility rule by 4 is to check the last two digits. If the last two digits are divisible by 4 then the whole number is divisible by 4. Get the examples of divisible by 4 to know more about divisibility rules.

## Divisible by 4 – Definition

A number is said to be divisible by 4 if the number is formed by its digits in tens place and units place. That means if the last two digits are divisible by 4 then the whole number is divisible by 4. Let us take an example to check the divisibility rule for 4 using the test of divisibility by 4.

**Example: **

Check whether 324 is divisible by 4.

Solution:

In 324 the last two digits on its extreme right side are 24 which is divisible by 4.

Hence 324 is divisible by 4.
