Divisor 8121

To determine if any number is divisible by 8121, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 2707 - then it is divisible by 8121.

The following tests must pass:

• Test if a number is divisible by 3
• The "Nathan Bosman Test" for Divisibility by 2707
