Divisor 18901

To determine if any number is divisible by 18901, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 41 and 461 - then it is divisible by 18901.

The following tests must pass:

• Test if a number is divisible by 41
• Test if a number is divisible by 461

Easy!
