Divisor 8506

To determine if any number is divisible by 8506, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 4253 - then it is divisible by 8506.

The following tests must pass:

• Test if a number is divisible by 2
• The "Douglas Ellison Test" for Divisibility by 4253
