Divisor 15701

To determine if any number is divisible by 15701, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 7 and 2243 - then it is divisible by 15701.

The following tests must pass:

• Test if a number is divisible by 7
• The "Shelvacu Test" for Divisibility by 2243
