Divisor 8665

To determine if any number is divisible by 8665, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 1733 - then it is divisible by 8665.

The following tests must pass:

• Test if a number is divisible by 5
• The "Alfie Prankard Test" for Divisibility by 1733
