Divisibility Rule of 664
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 664.
What is the Divisibility Rule of 664?
The divisibility rule for 664 is a method by which we can find out if a number is divisible by 664 or not without using the division method.
Check whether 1328 is divisible by 664 with the divisibility rule.
Step 1: Divide the number into groups starting from the right, each containing as many digits as there are in 664, which is three digits. Here, 1328 is divided into two groups: 1 and 328.
Step 2: Check if each group is divisible by 664.
Step 3: Since 328 is not divisible by 664 and neither is 1, 1328 is not divisible by 664. If all groups are divisible by 664, then the number is divisible by 664.
Tips and Tricks for Divisibility Rule of 664
Learn the divisibility rule to help with quick calculations. Let’s learn a few tips and tricks for the divisibility rule of 664.
- Know the multiples of 664: Memorize the multiples of 664 (664, 1328, 1992, 2656, etc.) to quickly check the divisibility. If each group of numbers is a multiple of 664, then the number is divisible by 664.
- Repeat the process for large numbers: Students should keep repeating the divisibility process by dividing into groups until they reach a small number or each group is divisible by 664.
- 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 664
The divisibility rule of 664 helps us to quickly check if the given number is divisible by 664, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to avoid errors.
Mistake 1
Not following the correct steps.
Students should follow the correct steps by dividing the number into groups and checking each group for divisibility by 664.
Mistake 2
Not repeating the process when the result is large.
Students often stop the process after they have got a large number not divisible by 664. The process should be repeated until we get the smallest group that is divisible by 664.
Mistake 3
Confusing the steps.
Students often confuse the steps or forget the steps. To avoid the error, students should practice regularly.
Mistake 4
Overlooking the use of the division method.
Use the division method to verify results and ensure accuracy.
Mistake 5
Relying solely on estimation.
While estimation is useful, always verify with the actual calculation to confirm divisibility.
