Divisibility Rule of 979

The divisibility rule for 979 is a method by which we can find out if a number is divisible by 979 or not without using the division method. Check whether 1958 is divisible by 979 with the divisibility rule.

Step 1: Divide the number into groups of three digits from the right. Here in 1958, we have two groups: 1 and 958.

Step 2: Multiply the group of digits other than the rightmost group by 1021. In this case, multiply 1 by 1021. 1 × 1021 = 1021

Step 3: Subtract the result from Step 2 from the rightmost group. 958 - 1021 = -63.

  If the result is zero or a multiple of 979, then the original number is divisible by 979. Since -63 is not a multiple of 979, 1958 is not divisible by 979.

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 979.

Know the multiples of 979: Memorize the multiples of 979 (979, 1958, 2937, etc.) to quickly check divisibility. If the subtraction result is a multiple of 979, then the number is divisible by 979.

Use absolute values for subtraction results: If the subtraction result is negative, consider it as a positive number for checking divisibility.

Repeat the process for large numbers:

Students should keep repeating the divisibility process until they reach a small number that is divisible by 979. For example, check if 2937 is divisible by 979 using the divisibility test. Divide the number into groups: 2 and 937. Multiply 2 by 1021: 2 × 1021 = 2042. Subtract 2042 from 937: 937 - 2042 = -1105. Since -1105 is not a multiple of 979, 2937 is not divisible by 979.

Use the division method to verify:

Students can use the division method as a way to verify and cross-check their results. This will help them verify and also learn.
