Divisor 20135

To determine if any number is divisible by 20135, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 4027 - then it is divisible by 20135.

The following tests must pass:

• Test if a number is divisible by 5
• The "Alyx Test" for Divisibility by 4027
