Divisibility Rule of 980

The divisibility rule for 980 is a method by which we can find out if a number is divisible by 980 or not without using the division method. Check whether 1960 is divisible by 980 with the divisibility rule.

Step 1: Check if the number is divisible by 2, 5, and 7, since 980 = 2 × 5 × 7 × 14. For a number to be divisible by 980, it should be divisible by these factors.

  - 1960 is even, so it is divisible by 2.
  - The last digit of 1960 is 0, so it is divisible by 5.
  - For divisibility by 7, use the rule: double the last digit and subtract it from the rest of the number. 196 - 0(2) = 196; 196 is divisible by 7.

Step 2: Check if the number is divisible by 14. Since 1960 passes all the checks for divisibility by 2, 5, 7, and 14, it is divisible by 980.
