Divisor 16793

To determine if any number is divisible by 16793, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 2399 - then it is divisible by 16793.

The following tests must pass:

• Test if a number is divisible by 7
• The "Piotr Jakuc Test" for Divisibility by 2399
