Divisor 3687

To determine if any number is divisible by 3687, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 1229 - then it is divisible by 3687.

The following tests must pass:

• Test if a number is divisible by 3
• The "Yanik-Pascal Förster Test" for Divisibility by 1229
