Divisor 18649

To determine if any number is divisible by 18649, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 17 and 1097 - then it is divisible by 18649.

The following tests must pass:

• Test if a number is divisible by 17
• The "Martijn van der Ven Test" for Divisibility by 1097
