Divisor 18151

To determine if any number is divisible by 18151, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 2593 - then it is divisible by 18151.

The following tests must pass:

• Test if a number is divisible by 7
• The "Dexter Test" for Divisibility by 2593
