Divisibility Rule of 427
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 427.
What is the Divisibility Rule of 427?
The divisibility rule for 427 is a method by which we can find out if a number is divisible by 427 without using the division method. Check whether 854 is divisible by 427 with the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 854, 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., 85 - 8 = 77.
Step 3: If the result from step 2 isn't a multiple of 427, then the number isn't divisible by 427. In this example, 77 is not a multiple of 427, so 854 is not divisible by 427.
Tips and Tricks for Divisibility Rule of 427
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 427.
Know the multiples of 427:
Memorize the multiples of 427 (427, 854, 1281, 1708, 2135, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 427, then the number is divisible by 427.
Use 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 427.
For example: Check if 2552 is divisible by 427 using the divisibility test.
Multiply the last digit by 2, i.e., 2 × 2 = 4.
Subtract the remaining digits excluding the last digit by 4, 255 - 4 = 251.
Still, 251 is not a multiple of 427, so 2552 is not divisible by 427.
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 427
