Divisibility Rule of 622
The divisibility rule is a way to determine 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 624.
What is the Divisibility Rule of 622?
The divisibility rule for 622 is a method to determine if a number is divisible by 622 without dividing. Let's check whether 1244 is divisible by 622 using its rule.
Step 1: Divide the number into two parts, the last digit and the rest. For 1244, the last digit is 4, and the rest is 124.
Step 2: Multiply the last digit by 62 (a factor of 622). 4 × 62 = 248.
Step 3: Add the result from Step 2 to the rest of the number. 124 + 248 = 372.
Step 4: If the result is divisible by 622, then the original number is also divisible by 622. Since 372 is not divisible by 622, 1244 is not divisible by 622.
Tips and Tricks for Divisibility Rule of 622
Learning divisibility rules helps kids master division. Here are a few tips and tricks for the divisibility rule of 622.
Know the factors of 622:
Memorize the factors of 622 (1, 2, 311, 622) to help quickly check divisibility. If the result from the addition is a multiple of 622, the number is divisible by 622.
Use negative numbers when needed:
If the result after subtraction is negative, consider its absolute value for checking divisibility.
Repeat the process for large numbers:
For large numbers, repeat the divisibility process until reaching a smaller number that can be easily checked for divisibility by 622.
Use the division method to verify:
Use the division method to crosscheck results and ensure accuracy.
Common Mistakes and How to Avoid Them in Divisibility Rule of 622

Mistake 1
Not following the correct steps.
Follow the correct steps of multiplying the last digit by 62 and adding the result to the remaining digits.
Mistake 2
Including the last digit in the wrong step.
Exclude the last digit when calculating the rest of the number before adding the result.
Mistake 3
Not repeating the process for large numbers.
Continue the process until reaching a smaller number that can be easily checked for divisibility.
Mistake 4
Ignoring negative values.
Consider negative values as positive when checking divisibility.
Mistake 5
Confusing the steps.
Practice regularly to remember the steps and avoid confusion.
Divisibility Rule of 622 Examples
Problem 1
Is 1866 divisible by 622?

Yes, 2488 is divisible by 622.
Explanation
For checking the divisibility of 2488 by 622:
1) Divide the number by 622.
2) 2488 ÷ 622 = 4.
3) Since the division results in a whole number with no remainder, 2488 is divisible by 622.
Problem 3
Is -3110 divisible by 622?
No, -3110 is not divisible by 622.
Explanation
To check if -3110 is divisible by 622:
1) Remove the negative sign and divide the number by 622.
2) 3110 ÷ 622 ≈ 5.
3) The division does not result in a whole number, thus -3110 is not divisible by 622.
Problem 4
Can 1244 be divisible by 622 following the divisibility rule?
Yes, 1244 is divisible by 622.
Explanation
To determine if 1244 is divisible by 622:
1) Divide 1244 by 622.
2) 1244 ÷ 622 = 2.
3) As the result is a whole number without a remainder, 1244 is divisible by 622.
Problem 5
Check the divisibility rule of 622 for 933.
No, 933 is not divisible by 622.
Explanation
To verify the divisibility:
1) Divide 933 by 622.
2) 933 ÷ 622 ≈ 1.5.
3) The result is not a whole number, therefore 933 is not divisible by 622.
