Divisor 11428

To determine if any number is divisible by 11428, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 2857 - then it is divisible by 11428.

The following tests must pass:

• Test if a number is divisible by 4
• The "Rick Barrett Test" for Divisibility by 2857
