You are given an array $a$ consisting of $n$ integers.

Your task is to say the number of such positive integers $x$ such that $x$ divides each number from the array. In other words, you have to find the number of common divisors of all elements in the array.

For example, if the array $a$ will be $[2, 4, 6, 2, 10]$, then $1$ and $2$ divide each number from the array (so the answer for this test is $2$).


-----Input-----

The first line of the input contains one integer $n$ ($1 \le n \le 4 \cdot 10^5$) — the number of elements in $a$.

The second line of the input contains $n$ integers $a_1, a_2, \dots, a_n$ ($1 \le a_i \le 10^{12}$), where $a_i$ is the $i$-th element of $a$.


-----Output-----

Print one integer — the number of such positive integers $x$ such that $x$ divides each number from the given array (in other words, the answer is the number of common divisors of all elements in the array).
