Divisor 11901

To determine if any number is divisible by 11901, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 3967 - then it is divisible by 11901.

The following tests must pass:

• Test if a number is divisible by 3
• The "Carl Löfgren Test" for Divisibility by 3967
