Divisor 12651

To determine if any number is divisible by 12651, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 4217 - then it is divisible by 12651.

The following tests must pass:

• Test if a number is divisible by 3
• The "Ell Hofmann Test" for Divisibility by 4217
