Divisibility Rule of 256
The divisibility rule is a way to determine 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 items. In this topic, we will learn about the divisibility rule of 256
What is the Divisibility Rule of 256?
The divisibility rule for 256 is a method by which we can find out if a number is divisible by 256 without using the division method. To check whether 131072 is divisible by 256 using the divisibility rule:
Step 1: Check the last three digits of the number. In 131072, the last three digits are 072.
Step 2: If the number formed by the last three digits (072) is divisible by 256, then the entire number is divisible by 256.
Step 3: Since 072 is not divisible by 256, the number 131072 is not divisible by 256.
Tips and Tricks for Divisibility Rule of 256
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 256.
- Know the multiples of 256: Memorize the multiples of 256 (256, 512, 768, 1024, etc.) to quickly check divisibility. If the last three digits form a number that is a multiple of 256, then the entire number is divisible by 256.
- 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 verify and also learn.
- Practice with large numbers: Students should keep practicing the divisibility process with large numbers to get comfortable with the rule.
Common Mistakes and How to Avoid Them in Divisibility Rule of 256

Divisibility Rule of 256 Examples
Problem 1
Is the number 1024 divisible by 256?
Yes, 1024 is divisible by 256.
Explanation
To determine if 1024 is divisible by 256, we can directly divide 1024 by 256.
1) Calculate 1024 ÷ 256 = 4.
2) The result is an integer, therefore 1024 is divisible by 256.
Problem 2
Check the divisibility of the number 5120 by 256.
Yes, 5120 is divisible by 256.
Explanation
We can check divisibility by looking at the last three digits of the number, as 256 is 2^8 and aligns with 3 binary digits (8 bits).
1) The last three digits of 5120 are 120.
2) 120 is not a multiple of 256, but since 5120 ends in three zeros, we can also directly divide: 5120 ÷ 256 = 20.
3) The result is an integer, which confirms that 5120 is divisible by 256.
Problem 3
Is 768 divisible by 256?
Yes, 768 is divisible by 256.
Explanation
To check if 768 is divisible by 256:
1) Divide 768 by 256.
2) Calculate 768 ÷ 256 = 3.
3) The result is an integer, thus 768 is divisible by 256.
Problem 4
Can 3000 be divisible by 256?
No, 3000 is not divisible by 256.
Explanation
To determine if 3000 is divisible by 256:
1) Check the last three digits: 000.
2) 000 is not a multiple of 256 on its own, but let's divide 3000 by 256 to confirm:
3) Calculate 3000 ÷ 256 ≈ 11.71875.
4) The result is not an integer, hence 3000 is not divisible by 256.
Problem 5
Check if the number 2048 is divisible by 256.
Yes, 2048 is divisible by 256.
Explanation
To verify divisibility of 2048 by 256:
1) Directly divide 2048 by 256.
2) Calculate 2048 ÷ 256 = 8.
3) The result is an integer, which confirms 2048 is divisible by 256.
