Divisor 3147

To determine if any number is divisible by 3147, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 1049 - then it is divisible by 3147.

The following tests must pass:

• Test if a number is divisible by 3
• The "Michael Salyer Test" for Divisibility by 1049
