Divisor 4647

To determine if any number is divisible by 4647, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 1549 - then it is divisible by 4647.

The following tests must pass:

• Test if a number is divisible by 3
• The "Stephen Coleman Test" for Divisibility by 1549
