Divisor 13071

To determine if any number is divisible by 13071, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 4357 - then it is divisible by 13071.

The following tests must pass:

• Test if a number is divisible by 3
• The "Margo Bergman Test" for Divisibility by 4357
