Divisor 19247

To determine if any number is divisible by 19247, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 19 and 1013 - then it is divisible by 19247.

The following tests must pass:

• Test if a number is divisible by 19
• The "Jonny Lundell Test" for Divisibility by 1013
