Divisor 23007

To determine if any number is divisible by 23007, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 7669 - then it is divisible by 23007.

The following tests must pass:

• Test if a number is divisible by 3
• The "Alex Rohrer Test" for Divisibility by 7669
