Which number serves as a counterexample all positive integers are divisible by 2 or 3?
Any Prime number (excluding 2 and 3 of course) would do, since these are not divisible by any number except 1 and itself.
So 5,7,11,13,...
Or products of prime numbers (again without 2 and 3)
For example
5*5=25
5*7=35
5*5*7=175
etc.
