Divisor 2218

To determine if any number is divisible by 2218, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 1109 - then it is divisible by 2218.

The following tests must pass:

• Test if a number is divisible by 2
• The "Gyrdon Test" for Divisibility by 1109
