Divisor 1967

To determine if any number is divisible by 1967, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 281 - then it is divisible by 1967.

The following tests must pass:

• Test if a number is divisible by 7
• Test if a number is divisible by 281

Easy!
