Rick is thinking of a positive factor of 14 and Steve is thinking of a positive factor of 424. If Rick and Steve are thinking of the same number, how many possible numbers could they be thinking of?

Prime factor of 14 = 2 * 7

Prime factor of 424 = 2^3 * 53

So common factors are 2. 

So either 1 or 2 are the possible numbers.
