Divisor 21884

To determine if any number is divisible by 21884, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 4 and 5471 - then it is divisible by 21884.

The following tests must pass:

• Test if a number is divisible by 4
• The "Andreas Hammargren Test" for Divisibility by 5471
