Divisibility Rule of 247
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 247.
What is the Divisibility Rule of 247?
The divisibility rule for 247 is a method by which we can find out if a number is divisible by 247 or not without using the division method. Check whether 494 is divisible by 247 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 494, 4 is the last digit, so 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., 49 - 8 = 41.
Step 3: As it is shown that 41 is not a multiple of 247, therefore, the number is not divisible by 247. If the result from Step 2 were a multiple of 247, then the number would be divisible by 247.
Tips and Tricks for Divisibility Rule of 247
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 247.
1. Know the multiples of 247:
Memorize the multiples of 247 (247, 494, 741, 988, etc.) to quickly check for divisibility. If the result from the subtraction is a multiple of 247, then the number is divisible by 247.
2. Use the negative numbers:
If the result we get after the subtraction is negative, we will ignore the symbol and consider it as positive for checking the divisibility of a number.
3. Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 247. For example: Check if 988 is divisible by 247 using the divisibility test. Multiply the last digit by 2, i.e., 8 × 2 = 16. Subtract the remaining digits excluding the last digit by 16, 98 - 16 = 82. Since 82 is not a multiple of 247, 988 is not divisible by 247.
4. 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 247
