. "NOTE: this will include 1 and n itself.Example: Finding the number of all factors of 450: \\(450=2^1*3^2*5^2\\)Total number of factors of 450 including 1 and 450 itself is \\((1+1)*(2+1)*(2+1)=2*3*3=18\\) factors.Back to the original question:The positive integer k has exactly two positive prime factors, 3 and 7." . . .
