Divisor 18027

To determine if any number is divisible by 18027, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 9 and 2003 - then it is divisible by 18027.

The following tests must pass:

• Test if a number is divisible by 9
• The "Dirk Franken Test" for Divisibility by 2003

Easy!
