Divisibility Rule of 988

The divisibility rule for 988 is a method by which we can determine if a number is divisible by 988 without performing the division method. Check whether 1976 is divisible by 988 with the divisibility rule.

Step 1: Divide the number into groups of three digits starting from the right. Here in 1976, it becomes 1,976.

Step 2: Consider only the last group of three digits for now, i.e., 976. Subtract it from the number formed by the remaining groups. Here, 1 - 976 = -975.

Step 3: Check if the result is a multiple of 988. If it is, the original number is divisible by 988. Since -975 is not a multiple of 988, 1976 is not divisible by 988.

Learn the divisibility rule to help master division. Let’s explore a few tips and tricks for the divisibility rule of 988.

Know the multiples of 988:

Memorize the first few multiples of 988 (988, 1976, 2964, 3952, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 988, then the number is divisible by 988.

Use absolute values:

If the subtraction result is negative, consider its absolute value for checking divisibility.

Repeat the process for large numbers:

Continue applying the divisibility process until reaching a smaller number that can easily be checked for divisibility by 988.

Use the division method to verify:

You can use the division method to verify and crosscheck results, reinforcing understanding.
