Divisibility Rule of 971
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 971.
What is the Divisibility Rule of 971?
The divisibility rule for 971 is a method by which we can find out if a number is divisible by 971 or not without using the division method. Check whether 185342 is divisible by 971 with the divisibility rule.
Step 1: Break down 971 into its prime factors, which are 7, 13, and 11. We will use these factors to check divisibility.
Step 2: To check if a number is divisible by 971, it must be divisible by 7, 13, and 11. Follow the divisibility rules for each of these numbers on 185342.
For 7: Double the last digit and subtract it from the rest of the number. Repeat the process if necessary.
For 13: Subtract 9 times the last digit from the rest of the number. Repeat the process if necessary.
For 11: Alternate subtracting and adding the digits of the number.
Step 3: If the number passes the divisibility test for 7, 13, and 11, it is divisible by 971. Otherwise, it is not.
Tips and Tricks for Divisibility Rule of 971
Learning divisibility rules will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 971.
Know the multiples of 971:
Memorize the multiples of 971 (971, 1942, 2913...etc.) to quickly check divisibility. If the result from the tests is a multiple of 971, then the number is divisible by 971.
Use negative numbers:
If the result we get after subtraction is negative, consider it as positive for checking divisibility.
Repeat the process for large numbers:
Students should keep repeating the divisibility process for 7, 13, and 11 until they reach a small number that is divisible by them. For example, to check if 185342 is divisible by 971, apply the rules for 7, 13, and 11.
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 verify and learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 971
The divisibility rule of 971 helps us quickly check if a given number is divisible by 971, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps for all factors.
Students should follow the correct steps for divisibility by 7, 13, and 11.
Divisibility Rule of 971 Examples
Problem 1
Is 2913 divisible by 971?
Yes, 2913 is divisible by 971.
Explanation
To check if 2913 is divisible by 971, we apply the rule as follows:
1) Multiply the last digit of the number by 3, 3 × 3 = 9.
2) Subtract the result from the remaining digits, excluding the last digit, 291 – 9 = 282.
3) Check if 282 is divisible by 971. Yes, 282 is divisible by 971 because 282 is 971 multiplied by 0.291 (282 / 971 = 0.291).
Problem 2
Check the divisibility rule of 971 for 5826.
No, 5826 is not divisible by 971.
Explanation
To verify if 5826 is divisible by 971:
1) Multiply the last digit by 3, 6 × 3 = 18.
2) Subtract the result from the remaining digits, 582 – 18 = 564.
3) Check if 564 is divisible by 971. No, 564 is not divisible by 971 since 564 divided by 971 is not an integer (564 / 971 ≈ 0.581).
Problem 3
Is 8739 divisible by 971?
No, 8739 is not divisible by 971.
Explanation
For divisibility of 8739 by 971, we ignore the negative sign:
1) Multiply the last digit by 3, 9 × 3 = 27.
2) Subtract the result from the remaining digits, 873 – 27 = 846.
3) Check if 846 is divisible by 971. No, 846 is not divisible by 971 as 846 divided by 971 is not an integer (846 / 971 ≈ 0.871).
Problem 4
Can 582 be divisible by 971 following the divisibility rule?
No, 582 is not divisible by 971.
Explanation
To determine if 582 is divisible by 971:
1) Multiply the last digit by 3, 2 × 3 = 6.
2) Subtract the result from the remaining digits, 58 – 6 = 52.
3) Check if 52 is divisible by 971. No, 52 is not divisible by 971 since 52 divided by 971 is not an integer (52 / 971 ≈ 0.0536).
Problem 5
Check the divisibility rule of 971 for 3884.
Yes, 3884 is divisible by 971.
Explanation
To verify if 3884 is divisible by 971:
1) Multiply the last digit by 3, 4 × 3 = 12.
2) Subtract the result from the remaining digits, 388 – 12 = 376.
3) Check if 376 is divisible by 971. Yes, 376 is divisible by 971 because 971 multiplied by 0.387 (376 / 971 = 0.387).
