Divisor 7053

To determine if any number is divisible by 7053, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 2351 - then it is divisible by 7053.

The following tests must pass:

• Test if a number is divisible by 3
• The "pirate-numbers Test" for Divisibility by 2351
