Divisor 25161

To determine if any number is divisible by 25161, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 8387 - then it is divisible by 25161.

The following tests must pass:

• Test if a number is divisible by 3
• The "Jordan Elder Test" for Divisibility by 8387
