Divisibility Rule of 108
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 108.
What is the Divisibility Rule of 108?
The divisibility rule for 108 is a method by which we can find out if a number is divisible by 108 or not without using the division method. Check whether 324 is divisible by 108 with the divisibility rule.
Step 1: Check if the number is divisible by 4. The last two digits of 324 are 24, and since 24 is divisible by 4, we move to the next step.
Step 2: Check if the number is divisible by 9. Add the digits of 324: 3 + 2 + 4 = 9. Since 9 is divisible by 9, 324 is divisible by 108.

Tips and Tricks for Divisibility Rule of 108
Learn the divisibility rule to help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 108.
- Know the multiples of 108: Memorize the multiples of 108 (108, 216, 324, 432, etc.) to quickly check the divisibility. If a number matches these multiples, it is divisible by 108.
- Use divisibility rules for smaller factors: Since 108 is made up of the factors 4 and 9, ensure a number is divisible by these smaller factors to confirm divisibility by 108.
- Repeat the process for large numbers: Students should keep repeating the divisibility process for both 4 and 9 until they reach a conclusion about the number's divisibility by 108.
- 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 108
The divisibility rule of 108 helps us to quickly check if the given number is divisible by 108, 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 following the correct steps.
Students should ensure they check divisibility by both 4 and 9 since 108 is divisible evenly by these numbers.
Mistake 2
Mistake 2: Ignoring one of the smaller factors.
Remember that a number must be divisible by both 4 and 9 to be divisible by 108.
Mistake 3
Not repeating the process for each component factor when the result is large.
Students should repeat the process for each factor until they get a result confirming divisibility by 108.
Mistake 4
Confusing the steps.
Students often confuse the steps or forget them; to avoid errors, students should practice regularly.

Divisibility Rule of 108 Examples
Problem 1
A charity event wants to distribute 216 raffle tickets evenly among 2 teams. Is it possible using the divisibility rule of 108?
Yes, 216 is divisible by 108.
Explanation
To check divisibility by 108, verify divisibility by 2, 3, and 4.
1) Divisibility by 2: The last digit is 6, which is even.
2) Divisibility by 3: Sum of the digits (2 + 1 + 6 = 9) is divisible by 3.
3) Divisibility by 4: The last two digits, 16, are divisible by 4.
Since 216 satisfies divisibility by 2, 3, and 4, it is divisible by 108.
Problem 2
A rectangular garden has a perimeter of 432 meters. Can the length of the garden be 108 meters, using the divisibility rule of 108?
Yes, 432 is divisible by 108.
Explanation
Check divisibility by 2, 3, and 4.
1) Divisibility by 2: The last digit is 2, which is even.
2) Divisibility by 3: Sum of the digits (4 + 3 + 2 = 9) is divisible by 3.
3) Divisibility by 4: The last two digits, 32, are divisible by 4.
Since 432 meets all criteria, it is divisible by 108.
Problem 3
A box contains 648 chocolates, and you want to pack them into smaller boxes, each holding 108 chocolates. Is this possible using the divisibility rule of 108?
Yes, 648 is divisible by 108.
Explanation
Verify divisibility by 2, 3, and 4.
1) Divisibility by 2: The last digit is 8, an even number.
2) Divisibility by 3: Sum of the digits (6 + 4 + 8 = 18) is divisible by 3.
3) Divisibility by 4: The last two digits, 48, are divisible by 4.
Thus, 648 is divisible by 108.

Problem 4
A library has 324 books to arrange in stacks of 108. Can this be done using the divisibility rule of 108?
Yes, 324 is divisible by 108.
Explanation
Check divisibility by 2, 3, and 4.
1) Divisibility by 2: The last digit is 4, even.
2) Divisibility by 3: Sum of the digits (3 + 2 + 4 = 9) is divisible by 3.
3) Divisibility by 4: The last two digits, 24, are divisible by 4.
Therefore, 324 is divisible by 108.
Problem 5
A festival organizer has 432 flags to distribute evenly among 4 locations. Is it possible using the divisibility rule of 108?
Yes, 432 is divisible by 108.
Explanation
Verify divisibility by 2, 3, and 4.
1) Divisibility by 2: The last digit is 2, which is even.
2) Divisibility by 3: Sum of the digits (4 + 3 + 2 = 9) is divisible by 3.
3) Divisibility by 4: The last two digits, 32, are divisible by 4.
Since all conditions are satisfied, 432 is divisible by 108.
