Divisor 19144

To determine if any number is divisible by 19144, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 8 and 2393 - then it is divisible by 19144.

The following tests must pass:

• Test if a number is divisible by 8
• The "Colin Test" for Divisibility by 2393
