Divisibility Rule of 128
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 128.
What is the Divisibility Rule of 128?
The divisibility rule for 128 is a method by which we can find out if a number is divisible by 128 or not without using the division method. Check whether 1024 is divisible by 128 with the divisibility rule.
Step 1: Check the last three digits of the number. If the last three digits form a number that is divisible by 128, then the entire number is divisible by 128. In 1024, the last three digits are 024.
Step 2: Since 024 (or simply 24) is not divisible by 128, the number 1024 is not divisible by 128.
Tips and Tricks for Divisibility Rule of 128
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 128.
- Know the multiples of 128: Memorize the multiples of 128 (128, 256, 384, 512, etc.) to quickly check divisibility. If the last three digits form a multiple of 128, then the number is divisible by 128.
- Repeat the process for large numbers: Students should apply the rule to the last three digits of large numbers to determine divisibility by 128.
- Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.
