Divisibility Rule of 455
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 455.
What is the Divisibility Rule of 455?
The divisibility rule for 455 is a method by which we can find out if a number is divisible by 455 or not without using the division method.
Check whether 910 is divisible by 455 with the divisibility rule.
Step 1: Check if the number is divisible by 5. Since the last digit of 910 is 0, it is divisible by 5.
Step 2: Check if the number is divisible by 7. To do this, double the last digit (0 × 2 = 0), subtract it from the rest of the number (91 - 0 = 91), and check if the result is a multiple of 7. Since 91 is 7 × 13, it is divisible by 7.
Step 3: Check if the number is divisible by 13. Since 91 divided by 13 equals 7, it is divisible by 13.
Since 910 is divisible by 5, 7, and 13, it is divisible by 455.
Tips and Tricks for Divisibility Rule of 455
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 455.
- Know the multiples of 455: Memorize the multiples of 455 (455, 910, 1365, 1820…etc.) to quickly check divisibility.
- Understand divisibility by factorization: Check divisibility by 5, 7, and 13 separately, as 455 = 5 × 7 × 13.
- Repeat the process for large numbers: Students should keep repeating the divisibility process for each factor until they reach a small number that is divisible by 455.
- 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.
