Divisibility Rule of 648
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 648.
What is the Divisibility Rule of 648?
The divisibility rule for 648 is a method by which we can find out if a number is divisible by 648 without using the division method. Check whether 7776 is divisible by 648 with the divisibility rule.
Step 1: Check if the number is divisible by 8. For 7776, the last three digits are 776, which is divisible by 8 (since 776 ÷ 8 = 97).
Step 2: Check if the number is divisible by 81. Sum the digits of 7776: 7+7+7+6 = 27, which is divisible by 9 (since 27 ÷ 9 = 3). Since 81 is a power of 9, repeat the process: 2+7 = 9, which is divisible by 9.
Step 3: Since 7776 is divisible by both 8 and 81, it is divisible by 648.
Tips and Tricks for Divisibility Rule of 648
Understanding the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 648.
- Know the multiples of 648: Memorize the multiples of 648 (648, 1296, 1944…etc.) to quickly check divisibility. If the result from the checks is a multiple of 648, then the number is divisible by 648.
- Use smaller checks: Break down the divisibility into smaller checks like checking for 8 and 81 separately, which are factors of 648.
- Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is clearly divisible by 648. For example, check if 12960 is divisible by 648.
Check divisibility by 8: The last three digits, 960, are divisible by 8 (960 ÷ 8 = 120).
Check divisibility by 81: The sum of the digits, 1+2+9+6+0 = 18, which is divisible by 9.
Since 12960 is divisible by both 8 and 81, it is divisible by 648.
- 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 confirm and also learn.
