Divisor 12013

To determine if any number is divisible by 12013, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 41 and 293 - then it is divisible by 12013.

The following tests must pass:

• Test if a number is divisible by 41
• Test if a number is divisible by 293
