Divisibility Rule of 122
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 divisibility rules for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 122.
What is the Divisibility Rule of 122?
The divisibility rule for 122 is a method by which we can find out if a number is divisible by 122 or not without using the division method. Check whether 2440 is divisible by 122 with the divisibility rule.
Step 1: Check if the number is divisible by 2. Here, 2440 ends with 0, which is even, so it is divisible by 2.
Step 2: Check if the number is divisible by 61. To do this, sum the digits of the number (2 + 4 + 4 + 0 = 10). Since 10 is not divisible by 61, 2440 is not divisible by 61.
Step 3: Since 2440 is divisible by 2 but not by 61, it is not divisible by 122.
Tips and Tricks for Divisibility Rule of 122
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 122.
- Know the factors of 122: 122 can be factored into 2 and 61. Ensure a number is divisible by both to be divisible by 122.
- Memorize multiples of 61: Knowing multiples of 61 (61, 122, 183, 244, etc.) can help quickly check divisibility.
- Use digit sum for 61: If the sum of the digits of a number is divisible by 61, then that number is divisible by 61.
- Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by both 2 and 61.
- 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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 122
The divisibility rule of 122 helps us to quickly check if a given number is divisible by 122, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not checking divisibility by both 2 and 61.
Ensure that the number is divisible by both 2 and 61 to confirm divisibility by 122.
Divisibility Rule of 122 Examples
Problem 1
Is 610 divisible by 122?
No, 610 is not divisible by 122.
Explanation
To check if 610 is divisible by 122:
1) Identify the nearest multiple of 122, which is 610/122 = 5 (since 122 x 5 = 610).
2) The number itself should be a perfect multiple, but since 610 doesn't evenly divide by 122, it’s not divisible by 122.
Problem 2
Check the divisibility rule of 122 for 732.
No, 732 is not divisible by 122.
Explanation
For checking divisibility, we look for the nearest multiple:
1) Divide 732 by 122, which gives approximately 6.
2) Check if 732 is exactly 122 x 6 = 732; since 732 is not equal to 732, it’s not divisible by 122.
Problem 3
Is 244 divisible by 122?
Yes, 244 is divisible by 122.
Explanation
1) Divide 244 by 122, which equals 2.
2) Since 244 = 122 x 2, it is divisible by 122
Problem 4
Can 366 be divisible by 122 following the divisibility rule?
Yes, 366 is divisible by 122.
Explanation
1) Divide 366 by 122, which equals 3.
2) Since 366 = 122 x 3, it is divisible by 122.
Problem 5
Check the divisibility rule of 122 for 488.
Yes, 488 is divisible by 122.
Explanation
1) Divide 488 by 122, which equals 4.
2) Since 488 = 122 x 4, it is divisible by 122.
