#568. Divine Divisor

統計

An integer $N > 1$ is given. We say that an integer $d > 1$ is a divisor of $N$ with multiplicity $k > 0$ ($k$ is integer) if $d^k \mid N$ and $d^{k+1}$ does not divide $N$. For example, the number $N=48=16x3$ has the following divisors: 2 with multiplicity 4, 3 with multiplicity 1, 4 with multiplicity 2, 6 with multiplicity 1, and so on.

We say that a number is a divine divisor of the number $N$ if $d$ is a divisor of $N$ with multiplicity $k$ and $N$ has no divisors with multiplicities greater than $k$. For example, the sole divine divisor of 48 is 2 (with multiplicity 4), and the divine divisors of 6 are: 2, 3 and 6 (each with multiplicity 1).

Your task is to determine the multiplicity of divine divisors of $N$ and the number of its divine divisors.

Input

The number $N$ is given on the standard input, though in a somewhat unusual way. The first line holds a single integer $n$ ($1 ≤ n ≤ 600$). The second line holds $n$ integers ai ($2 ≤ a_i ≤ 10^{18}$) separated by single spaces. These denote that $N=a_1 \cdot a_2 \cdot \ldots \cdot a_n$.

Output

The first line of the standard output should hold the maximum integer $k$ such that there exists a divisor $d$ of $N$ such that $d^k \mid N$. The second line should hold a single integer $D$ that is the number of (divine) divisors of $N$ with multiplicity $k$.
