Say I have a number, for example 212, is there a formula which will find me a prime factor, preferably the smallest or else the largest, of that number (without counting 1 or the number itself)? In this case it would be 2. Note that the smallest factor of a number (again, not counting 1 or the number itself) must be prime. And I don't want to use VBA if possible.
