Divisor 8981

To determine if any number is divisible by 8981, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 1283 - then it is divisible by 8981.

The following tests must pass:

• Test if a number is divisible by 7
• The "Sushiman Test" for Divisibility by 1283
