Divisibility Rule of 800

The divisibility rule for 800 is a method by which we can determine if a number is divisible by 800 without using the division method. Check whether 6400 is divisible by 800 using the divisibility rule.

Step 1: Check if the last three digits of the number are all zeros or if the last three digits form a number that is divisible by 8. Here in 6400, the last three digits are 400.

Step 2: Verify if 400 is divisible by 8. Divide 400 by 8 to check divisibility. 400 ÷ 8 = 50, which is an integer.

Step 3: Since the last three digits (400) can be divided by 8, the number 6400 is divisible by 800.

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 800.

Know the multiples of 800:

Memorize the multiples of 800 (800, 1600, 2400, 3200, etc.) to quickly check divisibility. If the last three digits form a multiple of 800, then the number is divisible by 800.

Use the round numbers:

Numbers ending in three zeros (e.g., 2000, 5000) are easy to check for divisibility by 800 as they are automatically divisible.

Repeat the process for large numbers:

For large numbers, focus on the last three digits. For example, check if 9800 is divisible by 800. The last three digits are 800, which is divisible by 8.

Use the division method to verify:

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

• Divisibility rule: A set of rules used to determine if a number is divisible by another number.
