Divisibility Rule of 931
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 931.
What is the Divisibility Rule of 931?
The divisibility rule for 931 is a method by which we can find out if a number is divisible by 931 or not without using the division method. Check whether 1862 is divisible by 931 with the divisibility rule.
Step 1: Multiply the last digit of the number by 3, here in 1862, 2 is the last digit, multiply it by 3. 2 × 3 = 6
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit, i.e., 186–6=180.
Step 3: As it is shown that 180 is not a multiple of 931, therefore, the number is not divisible by 931. If the result from step 2 was a multiple of 931, then the number would be divisible by 931.
Tips and Tricks for Divisibility Rule of 931
Learn the divisibility rule to help master division. Let’s learn a few tips and tricks for the divisibility rule of 931.
Know the multiples of 931:
Memorize the multiples of 931 (931, 1862, 2793, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 931, then the number is divisible by 931.
Use the negative numbers:
If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 931.
For example: Check if 3724 is divisible by 931 using the divisibility test.
Multiply the last digit by 3, i.e., 4 × 3 = 12.
Subtract the remaining digits excluding the last digit by 12, 372–12=360.
Since 360 is still a large number, repeat the process: Multiply the last digit by 3, 0 × 3=0.
Subtract 0 from the remaining numbers excluding the last digit, 36–0=36.
As 36 is not a multiple of 931, 3724 is not divisible by 931.
Use the division method to verify:
Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 931
The divisibility rule of 931 helps us to quickly check if the given number is divisible by 931, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not following the correct steps.
Students should follow the correct steps that are multiplying the last digit with 3 and then subtracting the result from the remaining digits excluding the last digit and checking whether it is a multiple of 931
Divisibility Rule of 931 Examples
Problem 1
Is 4655 divisible by 931?
Yes, 4655 is divisible by 931.
Explanation
To verify, use a hypothetical divisibility rule for 931.
1) Multiply the last digit of the number by 3, 5 × 3 = 15.
2) Subtract the result from the remaining digits, excluding the last digit, 465 – 15 = 450.
3) Check if 450 is a multiple of 931. Since 4655 is exactly 5 times 931, it is divisible by 931.
Problem 2
Check the divisibility rule of 931 for 1862.
No, 1862 is not divisible by 931.
Explanation
For checking the divisibility rule of 931 for 1862:
1) Multiply the last digit by 3, 2 × 3 = 6.
2) Subtract the result from the remaining digits, excluding the last digit, 186 – 6 = 180.
3) Check if 180 is a multiple of 931. It is not, so 1862 is not divisible by 931.
Problem 3
Is -3724 divisible by 931?
No, -3724 is not divisible by 931.
Explanation
To check if -3724 is divisible by 931, remove the negative sign and check the rule:
1) Multiply the last digit by 3, 4 × 3 = 12.
2) Subtract the result from the remaining digits, 372 – 12 = 360.
3) Check if 360 is a multiple of 931. It is not, so -3724 is not divisible by 931.
Problem 4
Can 2793 be divisible by 931 following the divisibility rule?
Yes, 2793 is divisible by 931.
Explanation
To check if 2793 is divisible by 931:
1) Multiply the last digit by 3, 3 × 3 = 9.
2) Subtract the result from the remaining digits, 279 – 9 = 270.
3) Check if 270 is a multiple of 931. Since 2793 is exactly 3 times 931, it is divisible by 931.
Problem 5
Check the divisibility rule of 931 for 5586.
Yes, 5586 is divisible by 931.
Explanation
To verify the divisibility rule for 5586:
1) Multiply the last digit by 3, 6 × 3 = 18.
2) Subtract the result from the remaining digits, 558 – 18 = 540.
3) Check if 540 is a multiple of 931. Since 5586 is exactly 6 times 931, it is divisible by 931.
