Divisibility Rule of 530

The divisibility rule for 530 is a method by which we can find out if a number is divisible by 530 without using the division method. Check whether 1590 is divisible by 530 with the divisibility rule.

Step 1: Check divisibility by 10. Since 1590 ends in 0, it is divisible by 10.

Step 2: Check divisibility by 53. Break down the number into digits. Multiply the first digit by 1, the second digit by 4, and the third digit by 3. Add up these results.

For 159, calculate 1 × 1 + 5 × 4 + 9 × 3 = 1 + 20 + 27 = 48.

Step 3: Check if the sum from step 2 is divisible by 53. Since 48 is not divisible by 53, 1590 is not divisible by 530.

Learning divisibility rules helps kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 530.

1. Know the multiples of 53:

   Memorize the multiples of 53 (53, 106, 159, etc.) to quickly check divisibility. If the result from the addition is a multiple of 53, then the number is divisible by 530.

2. 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.

3. Repeat the process for large numbers:

Students should keep repeating the divisibility process until they reach a small number that is divisible by 530.
