Divisor 20081

To determine if any number is divisible by 20081, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 43 and 467 - then it is divisible by 20081.

The following tests must pass:

• Test if a number is divisible by 43
• Test if a number is divisible by 467

Easy!
