Divisor 8728

To determine if any number is divisible by 8728, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 8 and 1091 - then it is divisible by 8728.

The following tests must pass:

• Test if a number is divisible by 8
• The "Richy_s Test" for Divisibility by 1091
