Divisor 1917

To determine if any number is divisible by 1917, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 27 and 71 - then it is divisible by 1917.

The following tests must pass:

• Test if a number is divisible by 27
• Test if a number is divisible by 71

Easy!
