Tell the factors

$p^n$ has $n+1$ factors, namely $1$ , $p$ , $p^2$ , $p^3$ , ..., $p^{n-1}$ , $p^n$ .

Due to the fundamental theorem of arithmetic, these are the only factors.

p^n has n+1 factors.
p is a prime number and n is any positive integer.
e.g.
3^2=9 has 3 factors 1,3,9.
7^3=343 has 4 factors 1,7,49,343.
Power of any prime number can be prime factorized into n numbers.(n is the power of the prime number)
And 1 is factor of every number. Hence there are n+1 factors of p^n.

@Harsh chaudhary problem is overrated !!!!!!!!
