Divisor 26507

To determine if any number is divisible by 26507, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 13 and 2039 - then it is divisible by 26507.

The following tests must pass:

• Test if a number is divisible by 13
• The "Fredrik Juhlin Test" for Divisibility by 2039

Easy!
