Divisor 18808

To determine if any number is divisible by 18808, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 8 and 2351 - then it is divisible by 18808.

The following tests must pass:

• Test if a number is divisible by 8
• The "pirate-numbers Test" for Divisibility by 2351
