Divisor 13017

To determine if any number is divisible by 13017, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 4339 - then it is divisible by 13017.

The following tests must pass:

• Test if a number is divisible by 3
• The "Rob Seymour Test" for Divisibility by 4339
