Divisor 4443

To determine if any number is divisible by 4443, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 1481 - then it is divisible by 4443.

The following tests must pass:

• Test if a number is divisible by 3
• The "Jean-Pierre Namink Test" for Divisibility by 1481
