Divisor 3194

To determine if any number is divisible by 3194, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 1597 - then it is divisible by 3194.

The following tests must pass:

• Test if a number is divisible by 2
• The "Jonathan O'Sullivan Test" for Divisibility by 1597
