Divisor 25003

To determine if any number is divisible by 25003, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 11 and 2273 - then it is divisible by 25003.

The following tests must pass:

• Test if a number is divisible by 11
• The "Zoey Test" for Divisibility by 2273
