Divisibility rule of 8 explained with examples

Learn and know divisibility rule of 8 in math. If we learn the divisibility rules it makes easy for us to identify which numbers are divisible by a number.

Divisibility rule of 8 explained with examples

Generally, without any divisibility rules also we can check whether the number is divisible by another number or not. But it is time taking process and suppose in any competitive exam if we apply normal method and check the number is divisible or not then definitely it is not a good move. In competitive exams we need to take less time to solve any problem. So if we learn divisibility rules, we can avoid time consuming. Now i will discuss about divisibility rule of 8 in detail.

What is the divisibility rule meaning in math?

In math, divisibility rule meaning is “it is one rule by which we can able to find or check whether the given number is divisible by another number or not? For example, the number 7321 is divisible by 9 or not? How to know? For this we should know the divisibility rule of 9.

The divisibility rule of 8 as follows

The divisibility rule of 8 is given as “if the last three digits of any number is divisible by 8 then we can say the given number is divisible by the 8”.

What numbers are divisible by the 8

In the two cases we can tell the numbers are divisible by 8 or not.

Suppose if a number is a multiple of 8, then definitely the number is divisible by 8. If it is not a multiple of 8 then the number is not divisible by 8.

If we don’t know whether the given number is multiple of 8 or not, then we have to use divisibility rule of 8 and we have find it.

Examples:

Is 3586 divisible by 8?

Solution:

According to divisibility rule of 8, the last three digits should be divisible by 8. Here the last 3 digits are 586. Check 586 is divisible by the number 8 or not. As 586 is not divisible by the number 8, so we can confirm that 3586 is not divisible by the number 8.
