Divisibility Rule of 804

The divisibility rule for 804 is a method by which we can find out if a number is divisible by 804 or not without using the division method. Check whether 3216 is divisible by 804 with the divisibility rule. 

Step 1: Divide the number into groups of three digits from the right. Here in 3216, we have two groups: 3 and 216.

Step 2: Check if each group is divisible by 804. In this example, check if 216 is divisible by 804. 

Step 3: Since 216 is less than 804 and not divisible by it, 3216 is not divisible by 804.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 804.

Know the multiples of 804:

Memorize the multiples of 804 (804, 1608, 2412, 3216…etc.) to quickly check the divisibility. If each group of three digits forms a number that is a multiple of 804, then the original number is divisible by 804.

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 verify and also learn.
