Divisibility Rule of 497
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 497.
What is the Divisibility Rule of 497?
The divisibility rule for 497 is a method by which we can determine if a number is divisible by 497 or not without using the division method. Check whether 994 is divisible by 497 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 994, 4 is the last digit, multiply it by 2. 4 × 2 = 8
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 99–8 = 91.
Step 3: As it is shown that 91 is not a multiple of 497, the number is not divisible by 497. If the result from step 2 were a multiple of 497, then the number would be divisible by 497.
Tips and Tricks for Divisibility Rule of 497
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 497.
- Know the multiples of 497: Memorize the multiples of 497 (497, 994, 1491, 1988, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 497, then the number is divisible by 497.
- 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 497.
For example: Check if 2485 is divisible by 497 using the divisibility test. Multiply the last digit by 2, i.e., 5 × 2 = 10.
Subtract the remaining digits excluding the last digit by 10, 248–10 = 238. Still, 238 is not a multiple of 497, so 2485 is not divisible by 497.
- 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 497
The divisibility rule of 497 helps us quickly check if the given number is divisible by 497, 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: multiplying the last digit with 2, subtracting the result from the remaining digits excluding the last digit, and checking whether it is a multiple of 497.
