Divisor 13097

To determine if any number is divisible by 13097, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 1871 - then it is divisible by 13097.

The following tests must pass:

• Test if a number is divisible by 7
• The "Paul Zagieboylo Test" for Divisibility by 1871
