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.

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.
