Divisor 15501

To determine if any number is divisible by 15501, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 5167 - then it is divisible by 15501.

The following tests must pass:

• Test if a number is divisible by 3
• The "Frederik Van Slycken Test" for Divisibility by 5167
