Divisor 18016

To determine if any number is divisible by 18016, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 32 and 563 - then it is divisible by 18016.

The following tests must pass:

• Test if a number is divisible by 32
• Test if a number is divisible by 563

Easy!
