Divisor 25115

To determine if any number is divisible by 25115, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 5023 - then it is divisible by 25115.

The following tests must pass:

• Test if a number is divisible by 5
• The "Patrick Oglesby Test" for Divisibility by 5023
