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.

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.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by 2 if the number ends with an even digit.

• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 128 are 128, 256, 384, 512, etc.

• Digits: Individual numbers that form a larger number; for example, in 1024, 1, 0, 2, and 4 are digits.
• Integer: An integer is a whole number that can be positive, negative, or zero.

• Verification: The process of confirming the accuracy of a result or calculation, such as using division to verify divisibility.
