Divisor 10805

To determine if any number is divisible by 10805, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 2161 - then it is divisible by 10805.

The following tests must pass:

• Test if a number is divisible by 5
• The "Michael Grace Test" for Divisibility by 2161
