If n is a positive integer, how many different factors n has?
1) N/5 is a prime number.

1) N/5 is a prime number.
2) N has only two different prime factors.
\(Statement 1:\) \(\frac{N}{5} = P\) , or\(N = 5*P\)
Now\(5\) is prime and if the other the prime no\(P = 5\) , then\(N = 5^2\) , hence we will have\((2+1) = 3\) factors: 1, 5 & 25
But if the other prime\(P = 3\) , then\(N = 5*3\) , hence we will have\((1+1)*(1+1) = 4\) factors: 1, 3, 5, 15
Hence\(Insufficient\)
\(Statement 2:\) let's assume two different prime factors are
