Divisor 12271

To determine if any number is divisible by 12271, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 1753 - then it is divisible by 12271.

The following tests must pass:

• Test if a number is divisible by 7
• The "William Stone Test" for Divisibility by 1753
