To determine if any number is divisible by 19636, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 4909 - then it is divisible by 19636.

The following tests must pass:

• Test if a number is divisible by 4
• The "Andy K Test" for Divisibility by 4909
