Divisibility Rule of 53
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 the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 53.
What is the Divisibility Rule of 53?
The divisibility rule for 53 is a method to find out if a number is divisible by 53 without using the division method. Check whether 5306 is divisible by 53 using the divisibility rule.
Step 1: Multiply the last digit of the number by 5. Here, in 5306, 6 is the last digit, so multiply it by 5. 6 × 5 = 30.
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 530 - 30 = 500.
Step 3: As 500 is not a multiple of 53, the number 5306 is not divisible by 53. If the result from step 2 is a multiple of 53, then the number is divisible by 53.
Tips and Tricks for Divisibility Rule of 53
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 53.
- Know the multiples of 53: Memorize the multiples of 53 (53, 106, 159, 212, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 53, then the number is divisible by 53.
- Use negative numbers: If the result we get after 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 53. For example, check if 10600 is divisible by 53 using the divisibility test. Multiply the last digit by 5: 0 × 5 = 0. Subtract the remaining digits excluding the last digit: 1060 - 0 = 1060. Repeat the process: 1060 has 0 as the last digit, so repeat the step, 0 × 5 = 0. Subtract 106 - 0 = 106. As 106 is a multiple of 53, 10600 is divisible by 53.
- 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 verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 53
The divisibility rule of 53 helps us quickly check if the given number is divisible by 53, but common mistakes like calculation errors can 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: multiply the last digit by 5 and then subtract the result from the remaining digits excluding the last digit, then check whether it is a multiple of 53.
Mistake 2
Including the last digit in subtraction.
Students should remember to 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 got a large number after subtraction. The process should be repeated until we get the smallest number that is divisible by 53.
Mistake 4
Not considering negative values.
Students should consider negative values as positive while checking for divisibility, as divisibility rules apply to negative values too.
Mistake 5
Confusing the steps
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
