Divisibility Rule of 32
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 32.
What is the Divisibility Rule of 32?
The divisibility rule for 32 is a method by which we can find out if a number is divisible by 32 or not without using the division method. Check whether 1024 is divisible by 32 with the divisibility rule.
Step 1: Look at the last five digits of the number. If the number has fewer than five digits, consider the entire number. In 1024, we consider all the digits since it has fewer than five digits.
Step 2: Check if this number (1024) is divisible by 32. Since 1024 is equal to 32 × 32, it is divisible by 32.
Step 3: If the result from Step 2 is a multiple of 32, then the number is divisible by 32. If not, the number is not divisible by 32.
Tips and Tricks for Divisibility Rule of 32
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 32.
- Know the multiples of 32: Memorize the multiples of 32 (32, 64, 96, 128, 160, etc.) to quickly check divisibility. If the result from the checking is a multiple of 32, then the number is divisible by 32.
- Practice with smaller numbers: Start with smaller numbers to get comfortable with identifying multiples of 32.
- Understand binary representation: Since 32 is a power of 2 (2^5), numbers that are divisible by 32 will have at least five trailing zeros in their binary representation.
- 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 32
The divisibility rule of 32 helps us to quickly check if the given number is divisible by 32, but common mistakes like calculation errors lead to incorrect results. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not checking the correct number of digits.
Ensure you are checking the last five digits of the number, or the entire number if it has fewer than five digits.
Divisibility Rule of 32 Examples
Problem 1
Is 1024 divisible by 32?
Yes, 1024 is divisible by 32.
Explanation
To check if 1024 is divisible by 32, we can use the fact that 32 is a power of 2 (2^5), and check the last five digits or equivalently, the entire number here. Since 1024 is exactly 32 times 32, it is divisible by 32.
Problem 2
Check the divisibility rule of 32 for 2016.
No, 2016 is not divisible by 32.
Explanation
To determine if 2016 is divisible by 32, check the last five digits. Since 2016 has only four digits, consider the whole number. Divide 2016 by 32, which does not result in an integer (2016 ÷ 32 = 63, remainder 0), hence it is not divisible by 32.
Problem 3
Is -2048 divisible by 32?
Yes, -2048 is divisible by 32.
Explanation
To check if -2048 is divisible by 32, consider the positive number 2048. Since the last five digits (the whole number here) are 2048, and 2048 ÷ 32 = 64 with no remainder, -2048 is divisible by 32.
Problem 4
Can 1500 be divisible by 32 following the divisibility rule?
No, 1500 is not divisible by 32.
Explanation
To check if 1500 is divisible by 32, examine the last five digits, or the whole number since it is less than 10000. Divide 1500 by 32 and get a quotient with a remainder (1500 ÷ 32 = 46, remainder 28), indicating it is not divisible by 32.
Problem 5
Check the divisibility rule of 32 for 8192.
Yes, 8192 is divisible by 32.
Explanation
To check if 8192 is divisible by 32, we can directly divide the number by 32. Since 8192 ÷ 32 = 256 with no remainder, the number is divisible by 32.
