Divisor 20036

To determine if any number is divisible by 20036, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 5009 - then it is divisible by 20036.

The following tests must pass:

• Test if a number is divisible by 4
• The "Frances Todd Test" for Divisibility by 5009
