Divisor 7972

To determine if any number is divisible by 7972, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 1993 - then it is divisible by 7972.

The following tests must pass:

• Test if a number is divisible by 4
• The "Bendik Vatne Test" for Divisibility by 1993
