Divisor 6861

To determine if any number is divisible by 6861, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 2287 - then it is divisible by 6861.

The following tests must pass:

• Test if a number is divisible by 3
• The "Matthew Thomas Test" for Divisibility by 2287
