Divisor 4286

To determine if any number is divisible by 4286, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 2143 - then it is divisible by 4286.

The following tests must pass:

• Test if a number is divisible by 2
• The "David James Test" for Divisibility by 2143
