I assume you mean
what is the minimum possible value of f(75p²).
Is it known if p is greater than 5?
If it is, would it be the number of distinct factors of 75 multiplied by 3 (6*3)=18, namely 1,3,5,15,25,75, then multiply each one by p, and then multiply each one by p².
For positive integer x, let f(x) be the function which returns the number of distinct positive factors of x. If p is a prime number, what is the minimum possible value of f(75p2)?

no its not given that it is greater than 5 but it must be an prime number
