The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 804.

What is the 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.

Tips and Tricks for Divisibility Rule of 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.
