Divisor 15063

To determine if any number is divisible by 15063, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 5021 - then it is divisible by 15063.

The following tests must pass:

• Test if a number is divisible by 3
• The "Grant Parish Test" for Divisibility by 5021
