To determine if any number is divisible by 8336, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 16 and 521 - then it is divisible by 8336.

The following tests must pass:

• Test if a number is divisible by 16
• Test if a number is divisible by 521
