Divisibility Rule of 804
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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 804
The divisibility rule of 804 helps us to quickly check if the given number is divisible by 804, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you understand.
Mistake 1
Not grouping the digits correctly.
Students should ensure they correctly divide the number into groups of three digits from the right.
Mistake 2
Ignoring the remainder when checking divisibility.
Students should remember that if any group of digits leaves a remainder when divided by 804, the entire number is not divisible by 804.
Mistake 3
Forgetting to verify with division.
Always verify the result by performing the actual division.
Mistake 4
Not considering the negative values.
Students might ignore negative values thinking divisibility rules don't apply to negative numbers. But the divisibility rule is applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
Divisibility Rule of 804 Examples
Problem 1
Is 2412 divisible by 804?

Problem 2
Check the divisibility rule of 804 for 1608.
Yes, 1608 is divisible by 804.
Explanation
For checking the divisibility of 1608 by 804, divide 1608 by 804. You get an exact quotient of 2, indicating that 1608 is divisible by 804.
Problem 3
Is 402 divisible by 804?
No, 402 is not divisible by 804.
Explanation
To check if 402 is divisible by 804, divide 402 by 804. The quotient is not an integer, and there is a remainder, indicating that 402 is not divisible by 804.
Problem 4
Can 4824 be divisible by 804 following the divisibility rule?
Yes, 4824 is divisible by 804.
Explanation
To check if 4824 is divisible by 804, divide 4824 by 804. This results in an exact quotient of 6 with no remainder, confirming that 4824 is divisible by 804.
Problem 5
Check the divisibility rule of 804 for 1206.
No, 1206 is not divisible by 804.
Explanation
To determine if 1206 is divisible by 804, divide 1206 by 804. The quotient is not a whole number, and a remainder exists, showing that 1206 is not divisible by 804.
