Divisor 27728

To determine if any number is divisible by 27728, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 16 and 1733 - then it is divisible by 27728.

The following tests must pass:

• Test if a number is divisible by 16
• The "Alfie Prankard Test" for Divisibility by 1733
