Divisor 7916

To determine if any number is divisible by 7916, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 1979 - then it is divisible by 7916.

The following tests must pass:

• Test if a number is divisible by 4
• The "Jonathan Raisin Test" for Divisibility by 1979
