Divisor 20197

To determine if any number is divisible by 20197, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 19 and 1063 - then it is divisible by 20197.

The following tests must pass:

• Test if a number is divisible by 19
• The "L0R3M Test" for Divisibility by 1063
