Divisibility Rule of 6
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 6.
What is the Divisibility Rule of 6?
The divisibility rule for 6 is a method by which we can find out if a number is divisible by 6 or not without using the division method. A number is divisible by 6 if it is divisible by both 2 and 3.
Check whether 204 is divisible by 6 with the divisibility rule.
Step 1: Check if the number is even. Since 204 ends with 4, which is even, it is divisible by 2.
Step 2: Add the digits of the number. 2 + 0 + 4 = 6.
Step 3: Check if the sum from Step 2 is a multiple of 3. Since 6 is a multiple of 3, 204 is divisible by 3.
Since 204 is divisible by both 2 and 3, it is divisible by 6.
Tips and Tricks for Divisibility Rule of 6
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 6.
Know the multiples of 6:
Memorize the multiples of 6 (6, 12, 18, 24, 30, etc.) to quickly check the divisibility.
Check divisibility by 2 and 3:
For a number to be divisible by 6, ensure it's divisible by both 2 (even numbers) and 3 (sum of digits is a multiple of 3).
Repeat the process for larger numbers:
Students should keep repeating the process of checking divisibility by 2 and 3 until they reach a conclusion.
Use the division method to verify:
Students can use the division method to verify and cross-check their results. This will help them confirm and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 6
The divisibility rule of 6 helps us quickly check if a given number is divisible by 6, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking both conditions.
Students should ensure that they check for divisibility by both 2 and 3, not just one of them.
Mistake 2
Miscalculating the sum of digits.
Be careful when adding the digits and double-check the sum to ensure accuracy.
Mistake 3
Forgetting to check for even numbers.
Always remember to check if the number is even since divisibility by 2 is a requirement.
Mistake 4
Ignoring large numbers.
Even with large numbers, the divisibility rule applies, so be sure to check both conditions.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. To avoid errors, practice regularly.
Divisibility Rule of 6 Examples
Problem 1
Can the number 234 be divided by 6 without leaving a remainder?
Yes, 234 is divisible by 6.
Explanation
To verify divisibility by 6, a number must be divisible by both 2 and 3.
1) Check divisibility by 2: The last digit is 4, which is even. Therefore, 234 is divisible by 2.
2) Check divisibility by 3: Sum the digits, 2 + 3 + 4 = 9. Since 9 is divisible by 3, 234 is also divisible by 3.
Since 234 satisfies both conditions, it is divisible by 6.
Problem 2
Is 525 divisible by 6?
No, 525 is not divisible by 6.
Explanation
To determine divisibility by 6, we check for divisibility by both 2 and 3.
1) Check divisibility by 2: The last digit is 5, which is odd. Therefore, 525 is not divisible by 2.
Since 525 is not divisible by 2, it cannot be divisible by 6, even though 525 is divisible by 3 (5 + 2 + 5 = 12, and 12 is divisible by 3).
Problem 3
Determine if -360 is divisible by 6.
Yes, -360 is divisible by 6.
Explanation
The criteria for divisibility by 6 are divisibility by both 2 and 3.
1) Check divisibility by 2: The last digit is 0, which is even, so -360 is divisible by 2.
2) Check divisibility by 3: Sum the digits without considering the negative sign, 3 + 6 + 0 = 9. Since 9 is divisible by 3, -360 is also divisible by 3.
Therefore, -360 meets both conditions and is divisible by 6.
Problem 4
Can the number 157 be divided by 6 according to the divisibility rule?
No, 157 is not divisible by 6.
Explanation
For divisibility by 6, the number must be divisible by both 2 and 3.
1) Check divisibility by 2: The last digit is 7, which is odd, so 157 is not divisible by 2.
Since 157 is not divisible by 2, it cannot be divisible by 6, even though 1 + 5 + 7 = 13, and 13 is not divisible by 3.
Problem 5
Is the number 480 divisible by 6?
Yes, 480 is divisible by 6.
Explanation
We need to verify divisibility by both 2 and 3.
1) Check divisibility by 2: The last digit is 0, which is even, so 480 is divisible by 2.
2) Check divisibility by 3: Sum the digits, 4 + 8 + 0 = 12. Since 12 is divisible by 3, 480 is also divisible by 3.
Since 480 is divisible by both 2 and 3, it is divisible by 6.
