Divisor 4414

To determine if any number is divisible by 4414, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 2207 - then it is divisible by 4414.

The following tests must pass:

• Test if a number is divisible by 2
• The "Stef Siekman Test" for Divisibility by 2207
