GMAT Data Sufficiency (DS) | Re: If v = (w)^2(y)(z), how many positive factors does v have?

Given : v =(w)^2(y)(z)
Required : Number of positive factors of v

We can find the number of factors of N = (x^a)*(y^b)*(z^c) if x, y and z are different prime numbers.
Number of factors = (a+1)(b+ 1)(c+1)

Statement 1 w, y and z are integers greater than 1
If w,y and z are prime, we can find the number of factors. If they are not, we cannot find.
