Divisor 9701

To determine if any number is divisible by 9701, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 89 and 109 - then it is divisible by 9701.

The following tests must pass:

• Test if a number is divisible by 89
• Test if a number is divisible by 109
