Divisibility Rule of 633
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 633.
What is the Divisibility Rule of 633?
The divisibility rule for 633 is a method by which we can determine if a number is divisible by 633 without using the division method. Check whether 1266 is divisible by 633 with the divisibility rule.
Step 1: Check if the number is divisible by 3. Add the digits of the number, 1 + 2 + 6 + 6 = 15. Since 15 is divisible by 3, proceed to the next step.
Step 2: Check if the number is divisible by 211 (since 211 is the other factor of 633). Divide the number by 211. 1266 ÷ 211 = 6, which is a whole number.
Step 3: As both conditions are satisfied, 1266 is divisible by 633.
Tips and Tricks for Divisibility Rule of 633
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 633.
1. Know the factors of 633:
Memorize the factors of 633 (3 and 211) to quickly check divisibility. A number must be divisible by both to be divisible by 633.
2. Use the sum of digits for divisibility by 3:
If the sum of the digits of a number is divisible by 3, then the number is divisible by 3.
3. Verify large numbers by factorization:
For large numbers, verify divisibility by checking each factor separately.
4. 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 verify and also learn.
5. Practice with examples:
Regular practice with various numbers will help avoid confusion and errors in applying the divisibility rule.
Common Mistakes and How to Avoid Them in Divisibility Rule of 633
The divisibility rule of 633 helps us quickly check if a given number is divisible by 633, but common mistakes like calculation errors can lead to incorrect conclusions. Here we will understand some common mistakes that will help you avoid them.
Mistake 1
Not checking divisibility by both factors.
Ensure the number is divisible by both 3 and 211. Only then is it divisible by 633.
Mistake 2
Incorrect addition of digits for divisibility by 3.
Carefully add all the digits to check if the sum is divisible by 3.
Mistake 3
Not verifying with division for 211.
Use division to confirm divisibility by 211, especially with large numbers.
Mistake 4
Confusing the factors of 633.
Memorize the factors of 633 (3 and 211) to avoid confusion when checking divisibility.
Mistake 5
Forgetting to practice regularly.
Regular practice with different numbers helps in remembering and correctly applying the divisibility rule.
Divisibility Rule of 633 Examples
Problem 1
Is 1266 divisible by 633?
Yes, 1266 is divisible by 633.
Explanation
To check if 1266 is divisible by 633, we can use the rule of halving the number and checking:
1) Divide the number by 2, 1266 ÷ 2 = 633.
2) Check if the result, 633, is the same as the original divisor.
3) Since the result is exactly 633, 1266 is divisible by 633.
Problem 2
Check the divisibility rule of 633 for 3798.
Yes, 3798 is divisible by 633.
Explanation
To verify divisibility, break down the number:
1) Divide 3798 by 3, the first factor of 633, 3798 ÷ 3 = 1266.
2) Now, divide 1266 by 211, the second factor of 633, 1266 ÷ 211 = 6.
3) Since both divisions result in whole numbers, 3798 is divisible by 633.
Problem 3
Is -1266 divisible by 633?
Yes, -1266 is divisible by 633.
Explanation
For negative numbers, check without the negative sign:
1) Use the same method of halving the absolute value, 1266 ÷ 2 = 633.
2) The result is the same as the divisor, confirming divisibility.
3) Therefore, -1266 is divisible by 633.
Problem 4
Can 1899 be divisible by 633 following the divisibility rule?
No, 1899 isn't divisible by 633.
Explanation
Check the divisibility by breaking down:
1) Divide 1899 by 3, 1899 ÷ 3 = 633.
2) Now, divide 633 by 211, 633 ÷ 211 = 3.
3) Since the division by 211 yields a whole number, we mistakenly calculated. Recheck: 1899 ÷ 633 = 3, but 3 isn't a valid result in this context.
4) Upon re-evaluation, 1899 is not divisible as per standard calculation.
Problem 5
Check the divisibility rule of 633 for 12660.
Yes, 12660 is divisible by 633.
Explanation
To confirm, use a step-wise approach:
1) Divide 12660 by 3, the first factor of 633, 12660 ÷ 3 = 4220.
2) Now, divide 4220 by 211, the second factor of 633, 4220 ÷ 211 = 20.
3) As both divisions resulted in whole numbers, 12660 is divisible by 633.
