Divisibility Rule of 331
The divisibility rule is a way to determine whether a number is divisible by another number without performing the division directly. In real life, we can use divisibility rules for quick calculations, dividing things evenly, and organizing items. In this topic, we will explore the divisibility rule of 331.
What is the Divisibility Rule of 331?
The divisibility rule for 331 is a method by which we can find out if a number is divisible by 331 without using the division method. Let's check whether 662 is divisible by 331 using this rule.
Step 1: Identify if there is a simple rule or pattern. In this case, there is no straightforward rule like for smaller numbers, so we need to verify directly or use known multiples if available.
Step 2: Since 662 is a small number, we can check directly or compare with known multiples of 331.
Step 3: Divide 662 by 331. If the result is an integer, then 662 is divisible by 331.
Tips and Tricks for Divisibility Rule of 331
Understanding divisibility rules helps children master division. Let's learn some tips and tricks for the divisibility rule of 331.
- Know the multiples of 331: Memorize the multiples of 331 (331, 662, 993, etc.) to quickly check divisibility. If the number matches any of these multiples, it is divisible by 331.
- Large numbers: For large numbers, compare with known multiples of 331 or perform direct division for verification.
- Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results, which aids in learning and verification.
Common Mistakes and How to Avoid Them in Divisibility Rule of 331
The divisibility rule of 331 helps us to quickly check if a given number is divisible by 331, 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 verifying with division.
Since there isn't a simple rule, it's essential to verify by division or compare with known multiples.
Mistake 2
Using incorrect multiples.
Ensure you refer to the correct multiples of 331 for verification.
Mistake 3
Confusing the steps.
Practice regularly and ensure understanding of the process to avoid confusion.
Mistake 4
Skipping steps for large numbers.
Break down large numbers and methodically check each divisibility condition.
Mistake 5
Miscalculating the sum of digits.
Double-check your addition when calculating the sum of digits for divisibility by 3 and 11.
Divisibility Rule of 331 Examples
Problem 1
Is 993 divisible by 331?
Yes, 993 is divisible by 331.
Explanation
To check if 993 is divisible by 331, consider breaking it down:
1) Divide 993 by 331 directly.
2) The result is exactly 3 (993 ÷ 331 = 3), which is an integer.
3) Therefore, 993 is divisible by 331.
Problem 2
Check the divisibility rule of 331 for 662.
Yes, 662 is divisible by 331.
Explanation
To check the divisibility of 662 by 331:
1) Divide 662 by 331 directly.
2) The result is exactly 2 (662 ÷ 331 = 2), which is an integer.
3) Hence, 662 is divisible by 331.
Problem 3
Is 1324 divisible by 331?
No, 1324 is not divisible by 331.
Explanation
To determine if 1324 is divisible by 331:
1) Divide 1324 by 331 directly.
2) The result is approximately 4 (1324 ÷ 331 ≈ 4), but not an exact integer.
3) Therefore, 1324 is not divisible by 331.
Problem 4
Can 1986 be divisible by 331 following the divisibility rule?
Yes, 1986 is divisible by 331.
Explanation
To check divisibility of 1986 by 331:
1) Divide 1986 by 331 directly.
2) The result is exactly 6 (1986 ÷ 331 = 6), which is an integer.
3) Therefore, 1986 is divisible by 331.
Problem 5
Check the divisibility rule of 331 for 2648.
No, 2648 is not divisible by 331.
Explanation
To verify if 2648 is divisible by 331:
1) Divide 2648 by 331 directly.
2) The result is approximately 8 (2648 ÷ 331 ≈ 8), but not an exact integer.
3) Hence, 2648 is not divisible by 331.
