Divisibility Rule of 672
The divisibility rule is a way to determine whether a number is divisible by another number without using the division method. 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 672.
What is the Divisibility Rule of 672?
The divisibility rule for 672 is a method by which we can find out if a number is divisible by 672 or not without using the division method.
Let's check whether 1344 is divisible by 672 using the divisibility rule.
Step 1: Check if the number is divisible by 2, 3, and 7 (since 672 = 2^5 × 3 × 7).
For divisibility by 2: The number must be even. 1344 is even, so it passes this check.
For divisibility by 3: Sum the digits of the number; if the sum is divisible by 3, so is the number. 1 + 3 + 4 + 4 = 12, which is divisible by 3.
For divisibility by 7: Take the last digit, double it, and subtract from the rest of the number. 134 - 8 = 126; since 126 is divisible by 7, so is 1344.
Step 2: Since 1344 is divisible by 2, 3, and 7, it is divisible by 672.
Tips and Tricks for Divisibility Rule of 672
Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 672.
- Know the multiples of 672: Memorize the multiples of 672 (672, 1344, 2016, etc.) to quickly check divisibility. If a number is a multiple of 672, then it is divisible by 672.
- Combine divisibility rules: To check divisibility by 672, verify divisibility by 2, 3, and 7. If a number passes all these checks, it is divisible by 672.
- Repeat the divisibility checks for large numbers: For large numbers, verify divisibility by 2, 3, and 7 repeatedly until a conclusion is reached.
- Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This helps reinforce understanding.
Common Mistakes and How to Avoid Them in Divisibility Rule of 672
The divisibility rule of 672 helps us quickly check if the given number is divisible by 672, 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 all components (2, 3, and 7).
Ensure you check divisibility by 2, 3, and 7.
Mistake 2
Incorrect calculation of sum of digits for divisibility by 3.
Carefully add the digits and verify the sum is divisible by 3.
Mistake 3
Not doubling the last digit correctly in the divisibility check for 7.
Double the last digit accurately and then perform the subtraction.
Mistake 4
Confusing which divisibility checks are needed.
Remember that for 672, you need to check for 2, 3, and 7.
Mistake 5
Stopping early without completing all checks.
Ensure all divisibility rules are applied before concluding.
