Divisor 24427

To determine if any number is divisible by 24427, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 13 and 1879 - then it is divisible by 24427.

The following tests must pass:

• Test if a number is divisible by 13
• The "Craig Bonsignore Test" for Divisibility by 1879
