Divisor 28011

To determine if any number is divisible by 28011, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 3 and 9337 - then it is divisible by 28011.

The following tests must pass:

• Test if a number is divisible by 3
• The "Stephen Pritchard Test" for Divisibility by 9337
