Divisor 20901

To determine if any number is divisible by 20901, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 6967 - then it is divisible by 20901.

The following tests must pass:

• Test if a number is divisible by 3
• The "JustSomeGuy Test" for Divisibility by 6967
