Divisor 14139

To determine if any number is divisible by 14139, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 9 and 1571 - then it is divisible by 14139.

The following tests must pass:

• Test if a number is divisible by 9
• The "Adrian I Test" for Divisibility by 1571
