Divisor 8312

To determine if any number is divisible by 8312, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 8 and 1039 - then it is divisible by 8312.

The following tests must pass:

• Test if a number is divisible by 8
• The "Roman Test" for Divisibility by 1039
