Divisibility Rule of 531
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 531.
What is the Divisibility Rule of 531?
The divisibility rule for 531 is a method by which we can find out if a number is divisible by 531 or not without using the division method. Check whether 1593 is divisible by 531 with the divisibility rule.
Step 1: Multiply the last digit of the number by 3, here in 1593, 3 is the last digit. Multiply it by 3. 3 × 3 = 9
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 159–9 = 150.
Step 3: As it is shown that 150 is a multiple of 531, the number is divisible by 531. If the result from step 2 isn't a multiple of 531, then the number isn't divisible by 531.
Tips and Tricks for Divisibility Rule of 531
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 531.
Know the multiples of 531:
Memorize the multiples of 531 (531, 1062, 1593, 2124…etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 531, then the number is divisible by 531.
Use negative numbers:
If the result we get after the subtraction is negative, we will avoid the sign 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 531. For example, check if 2655 is divisible by 531 using the divisibility test. Multiply the last digit by 3, i.e., 5 × 3 = 15. Subtract from the remaining digits excluding the last digit, 265–15 = 250. Still, 250 is a large number, hence we will repeat the process again and multiply the last digit by 3, 0 × 3 = 0. Now subtracting 0 from the remaining numbers excluding the last digit, 25–0 = 25. As 25 is not a multiple of 531, 2655 is not divisible by 531.
Use the division method to verify:
Students can use the division method as a way to verify and cross-check their results. This will help them to verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 531
The divisibility rule of 531 helps us to quickly check if the given number is divisible by 531, 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.
Students should follow the correct steps that are multiplying the last digit by 3 and then subtracting the result from the remaining digits excluding the last digit and checking whether it is a multiple of 531.
Mistake 2
Including the last digit in subtraction.
Students should keep in mind that they should exclude the last digit while subtracting and include all the remaining digits.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after they have a large number as a result after subtraction. The process should be repeated until we get the smallest number that is divisible by 531.
Mistake 4
Not considering negative values.
Students consider negative values thinking divisibility rules don't apply to negative values. But the divisibility rule is applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
Divisibility Rule of 531 Examples
Problem 1
Is 2124 divisible by 531?
No, 2124 is not divisible by 531.
Explanation
To check the divisibility of 2124 by 531, follow these steps:
1) Multiply the last digit of the number (4) by 3, which gives 12.
2) Subtract this result from the number formed by the remaining digits (212), resulting in 212 - 12 = 200.
3) 200 is not a multiple of 531, so 2124 is not divisible by 531.
Problem 2
Check the divisibility rule of 531 for 5310.
Yes, 5310 is divisible by 531.
Explanation
To verify if 5310 is divisible by 531:
1) Multiply the last digit (0) by 3, resulting in 0.
2) Subtract this from the number formed by the other digits (531), giving 531 - 0 = 531.
3) Since 531 is a multiple of 531 (531 x 1 = 531), 5310 is divisible by 531.
Problem 3
Is -2655 divisible by 531?
Yes, -2655 is divisible by 531.
Explanation
To determine if -2655 is divisible by 531, ignore the negative sign and apply the rule:
1) Multiply the last digit (5) by 3, which gives 15.
2) Subtract this from the rest of the number (265), resulting in 265 - 15 = 250.
3) The result is not a direct multiple of 531, so verify further: 2655 divided by 531 equals 5, which is an integer, confirming that -2655 is divisible by 531.
Problem 4
Can 1239 be divisible by 531 following the divisibility rule?
No, 1239 is not divisible by 531.
Explanation
To check the divisibility of 1239 by 531:
1) Multiply the last digit (9) by 3, giving 27.
2) Subtract this from the number formed by the other digits (123), resulting in 123 - 27 = 96.
3) Since 96 is not a multiple of 531, 1239 is not divisible by 531.
Problem 5
Check the divisibility rule of 531 for 1593.
Yes, 1593 is divisible by 531.
Explanation
To verify if 1593 is divisible by 531:
1) Multiply the last digit (3) by 3, resulting in 9.
2) Subtract this from the number formed by the other digits (159), giving 159 - 9 = 150.
3) Since 150 is not an immediate multiple of 531, verify by division: 1593 divided by 531 equals 3, which is an integer, confirming that 1593 is divisible by 531.
