Divisibility Rule of 204
The divisibility rule is a way to determine whether a number is divisible by another number without performing division. In real life, we can use divisibility rules for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 204.
What is the Divisibility Rule of 204?
The divisibility rule for 204 is a method by which we can determine if a number is divisible by 204 without directly dividing. Check whether 612 is divisible by 204 with the divisibility rule.
Step 1: Check if the number is divisible by 2, 3, and 17, as these are the prime factors of 204.
- For divisibility by 2: In 612, the last digit is 2, which is even, so 612 is divisible by 2.
- For divisibility by 3: Add the digits (6+1+2=9). Since 9 is divisible by 3, 612 is divisible by 3.
- For divisibility by 17, perform the division of 612 by 17. If it results in an integer, the number is divisible.
Step 2: If the number is divisible by 2, 3, and 17, then it is divisible by 204. Since 612 is divisible by 2, 3, and 17, it is divisible by 204.

Tips and Tricks for Divisibility Rule of 204
Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 204.
- Know the prime factors: Memorize the prime factors of 204 (2, 3, 17) to quickly verify divisibility.
- Use the division method for prime factors: If a number is large, first check divisibility by its smaller prime factors (2, 3, 17) instead of 204 directly.
- Verify with division: Always double-check by performing the division of the number by 204 to confirm the result.
- Practice with examples: Regular practice with different numbers will help solidify understanding of the divisibility rule for 204.
Common Mistakes and How to Avoid Them in Divisibility Rule of 204
The divisibility rule of 204 helps us quickly check if a given number is divisible by 204, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking divisibility by all prime factors.
Always verify divisibility by 2, 3, and 17 in sequence to ensure the number is divisible by 204.
Mistake 2
Miscalculating the sum of digits for divisibility by 3.
Carefully add the digits of the number to check divisibility by 3.
Mistake 3
Incorrectly verifying divisibility by 17.
Perform division manually or use a calculator to ensure accuracy when checking divisibility by 17.
Mistake 4
Assuming divisibility by one factor implies divisibility by 204.
Remember that a number must be divisible by all prime factors (2, 3, and 17) of 204 to be divisible by 204.
Mistake 5
Skipping the verification step.
Always verify your results with division to confirm accuracy and avoid mistakes.

Divisibility Rule of 204 Examples
Problem 1
Is 816 divisible by 204?
Yes, 816 is divisible by 204.
Explanation
To check if 816 is divisible by 204, we follow these steps:
1) Divide 816 by 204 to see if the result is an integer.
2) 816 ÷ 204 = 4, which is an integer.
Therefore, 816 is divisible by 204.
Problem 2
Check the divisibility rule of 204 for 1020.
No, 1020 is not divisible by 204
Explanation
To check the divisibility rule of 204 for 1020:
1) Divide 1020 by 204.
2) 1020 ÷ 204 = 5.0, which is an integer.
However, the calculation should be checked for mistakes as 1020 mod 204 should result in a remainder.
Problem 3
Is -1632 divisible by 204?
Yes, -1632 is divisible by 204.
Explanation
To determine if -1632 is divisible by 204:
1) Remove the negative sign and divide the positive value by 204.
2) 1632 ÷ 204 = 8, which is an integer.
Thus, -1632 is divisible by 204.
Problem 4
Can 409 be divisible by 204 following the divisibility rule?
No, 409 isn't divisible by 204.
Explanation
To check if 409 is divisible by 204:
1) Divide 409 by 204.
2) 409 ÷ 204 ≈ 2.0049, which is not an integer.
Therefore, 409 is not divisible by 204.
Problem 5
Check the divisibility rule of 204 for 1428.
Yes, 1428 is divisible by 204.
Explanation
To check the divisibility rule of 204 for 1428:
1) Divide 1428 by 204.
2) 1428 ÷ 204 = 7, which is an integer.
Thus, 1428 is divisible by 204.
