Divisibility Rule of 422
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 422.
What is the Divisibility Rule of 422?
The divisibility rule for 422 is a method by which we can find out if a number is divisible by 422 or not without using the division method. Check whether 844 is divisible by 422 with the divisibility rule.
Step 1: Divide the number into two equal parts. Here in 844, split it into 84 and 4.
Step 2: Check if the first part (84) can be evenly divided by 2. If not, the number is not divisible by 422. Since 84 ÷ 2 = 42, proceed.
Step 3: Check if the second part (4) is 22 or a multiple of 22. Since 4 is not, the number is not divisible by 422.
Tips and Tricks for Divisibility Rule of 422
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 422.
Know the multiples of 422:
Memorize the multiples of 422 (422, 844, 1266, 1688…etc.) to quickly check the divisibility. If the number is a multiple of 422, then it is divisible by 422.
Use modular arithmetic:
If you are familiar with modular arithmetic, you can use it to check divisibility by 422 more efficiently.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is divisible by 422. For example, check if 2110 is divisible by 422.
- Split into 211 and 0.
- Check if 211 ÷ 2 = 105.5, which is not an integer, so 2110 is not divisible by 422.
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 their findings and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 422
The divisibility rule of 422 helps us quickly check if the given number is divisible by 422, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps of dividing the number into two parts and checking the divisibility of each part appropriately.
Mistake 2
Including the last digit in the wrong part.
Ensure that the division of the number is done correctly into two equal parts.
Mistake 3
Not checking both conditions.
Students often forget to check both parts for divisibility. Ensure both conditions are verified.
Mistake 4
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.
Mistake 5
Not considering the negative values.
Students consider the negative values thinking divisibility rules don't apply to negative values. But divisibility rules are applicable for negative values too. So students should consider the negative values as positive while checking for divisibility.
Divisibility Rule of 422 Examples
Problem 1
Is 844 divisible by 422?
Yes, 844 is divisible by 422.
Explanation
To check if 844 is divisible by 422, we use the divisibility rule.
1) Divide the number by 422 directly.
2) 844 ÷ 422 = 2.
3) Since the result is an integer, 844 is divisible by 422.
Problem 2
Check the divisibility rule of 422 for 1266.
Yes, 1266 is divisible by 422.
Explanation
To determine if 1266 is divisible by 422:
1) Divide the number by 422 directly.
2) 1266 ÷ 422 = 3.
3) Since the quotient is a whole number, 1266 is divisible by 422.
Problem 3
Is 211 not divisible by 422?
Correct, 211 is not divisible by 422.
Explanation
To verify if 211 is divisible by 422:
1) Divide the number by 422 directly.
2) 211 ÷ 422 = 0.5.
3) The result is not an integer, so 211 is not divisible by 422.
Problem 4
Can 0 be divisible by 422?
Yes, 0 is divisible by 422.
Explanation
According to the divisibility rule:
1) Any number divided by a non-zero number results in 0 if the dividend is 0.
2) 0 ÷ 422 = 0.
3) Since the division results in a whole number, 0 is divisible by 422.
Problem 5
Check the divisibility rule of 422 for 4220.
Yes, 4220 is divisible by 422.
Explanation
To confirm if 4220 is divisible by 422:
1) Divide the number by 422 directly.
2) 4220 ÷ 422 = 10.
3) The quotient is an integer, indicating that 4220 is divisible by 422.
