What is the Divisibility Rule of 8?

The divisibility rule for 8 is a method by which we can find out if a number is divisible by 8 or not without using the division method. Check whether 4,816 is divisible by 8 with the divisibility rule.

 

Step 1: Consider the last three digits of the number. Here, in 4,816, the last three digits are 816.

 

Step 2: Check if 816 is divisible by 8. Since 816 divided by 8 equals 102, which is an integer, 816 is divisible by 8.

 

Step 3: As it is shown that the last three digits are divisible by 8, the entire number (4,816) is divisible by 8.

Tips and Tricks for Divisibility Rule of 8

Learn the divisibility rule to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 8.

 

Know the multiples of 8:

Memorize the multiples of 8 (8, 16, 24, 32, 40, etc.) to quickly check divisibility. If the last three digits form a number that is a multiple of 8, then the entire number is divisible by 8.

 

Use the last three digits:

Focus only on the last three digits of a number to determine divisibility by 8. This simplifies the process significantly.

 

Repeat the process for large numbers:

If the number is too large, break it into parts and apply the rule to the last three digits of each part. For example, check if 45,472 is divisible by 8. The last three digits are 472, and since 472 divided by 8 equals 59, which is an integer, 45,472 is divisible by 8.

 

Use the division method to verify:

Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
