Divisor 22033

To determine if any number is divisible by 22033, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 11 and 2003 - then it is divisible by 22033.

The following tests must pass:

• Test if a number is divisible by 11
• The "Dirk Franken Test" for Divisibility by 2003
