Divisor 22151

To determine if any number is divisible by 22151, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 17 and 1303 - then it is divisible by 22151.

The following tests must pass:

• Test if a number is divisible by 17
• The "Alex Guichet Test" for Divisibility by 1303
