Divisor 2602

To determine if any number is divisible by 2602, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 2 and 1301 - then it is divisible by 2602.

The following tests must pass:

• Test if a number is divisible by 2
• The "Thomas Bartelmess Test" for Divisibility by 1301
