Divisor 4479

To determine if any number is divisible by 4479, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 1493 - then it is divisible by 4479.

The following tests must pass:

• Test if a number is divisible by 3
• The "Carl Test" for Divisibility by 1493
