"Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary" - Steve Jobs

Your number has a prime factorization of 3¹ 4² p¹, so it has (1+1) * (2+1) * (1+1) = 12 unique factors.

It has THREE unique primes (2, 3, p) and TWO invalid factors (1, n), so 12 - 3 - 2 = 7.

This is easily checked by choosing a p value, e.g. p = 5. 3 * 4 * 5 = 60, which has the factors 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60. The factors we want are 4, 6, 10, 12, 15, 20, and 30, so there are 7.
