To determine if any number is divisible by 3456, you must apply 2 tests successively. If all of them 'pass' - that is, if your number is divisible by 128 and 27 - then it is divisible by 3456.

The following tests must pass:

• Test if a number is divisible by 128
• Test if a number is divisible by 27
