Divisor 23061

To determine if any number is divisible by 23061, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 7687 - then it is divisible by 23061.

The following tests must pass:

• Test if a number is divisible by 3
• The "Derek Test" for Divisibility by 7687
