Divisor 20767

To determine if any number is divisible by 20767, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 19 and 1093 - then it is divisible by 20767.

The following tests must pass:

• Test if a number is divisible by 19
• The "Phil Jameson Test" for Divisibility by 1093

Easy!
