Divisor 15508

To determine if any number is divisible by 15508, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 3877 - then it is divisible by 15508.

The following tests must pass:

• Test if a number is divisible by 4
• The "Chris Fortenbach Test" for Divisibility by 3877
