Divisor 14989

To determine if any number is divisible by 14989, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 13 and 1153 - then it is divisible by 14989.

The following tests must pass:

• Test if a number is divisible by 13
• The "Guillaume Lederrey Test" for Divisibility by 1153
