Divisor 20199

To determine if any number is divisible by 20199, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 6733 - then it is divisible by 20199.

The following tests must pass:

• Test if a number is divisible by 3
• The "Sebastien Lavoie Test" for Divisibility by 6733
