Divisor 20836

To determine if any number is divisible by 20836, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 5209 - then it is divisible by 20836.

The following tests must pass:

• Test if a number is divisible by 4
• The "Till-Farin Metge Test" for Divisibility by 5209
