Divisor 27009

To determine if any number is divisible by 27009, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 9 and 3001 - then it is divisible by 27009.

The following tests must pass:

• Test if a number is divisible by 9
• The "Jonas Fischer Test" for Divisibility by 3001
