Divisor 15905

To determine if any number is divisible by 15905, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 5 and 3181 - then it is divisible by 15905.

The following tests must pass:

• Test if a number is divisible by 5
• The "Daniel Grøn Bjørneboe Test" for Divisibility by 3181
