Divisor 20077

To determine if any number is divisible by 20077, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 17 and 1181 - then it is divisible by 20077.

The following tests must pass:

• Test if a number is divisible by 17
• The "Jeremy Green Test" for Divisibility by 1181
