Divisor 7131

To determine if any number is divisible by 7131, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 2377 - then it is divisible by 7131.

The following tests must pass:

• Test if a number is divisible by 3
• The "Dan Senatore Test" for Divisibility by 2377
