Divisor 11105

To determine if any number is divisible by 11105, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 2221 - then it is divisible by 11105.

The following tests must pass:

• Test if a number is divisible by 5
• The "Florian K Test" for Divisibility by 2221

Easy!
