Divisor 1417

To determine if any number is divisible by 1417, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 13 and 109 - then it is divisible by 1417.

The following tests must pass:

• Test if a number is divisible by 13
• Test if a number is divisible by 109
