Divisor 8141

To determine if any number is divisible by 8141, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 1163 - then it is divisible by 8141.

The following tests must pass:

• Test if a number is divisible by 7
• The "Michal Kobelka Test" for Divisibility by 1163

Easy!
