Problem: Today Pari and Arya are playing a game called Remainders.

Pari chooses two positive integer x and k, and tells Arya k but not x. Arya have to find the value <image>. There are n ancient numbers c1, c2, ..., cn and Pari has to tell Arya <image> if Arya wants. Given k and the ancient values, tell us if Arya has a winning strategy independent of value of x or not. Formally, is it true that Arya can understand the value <image> for any positive integer x?

Note, that <image> means the remainder of x after dividing it by y.

Input

The first line of the input contains two integers n and k (1 ≤ n, k ≤ 1 000 000) — the number of ancient integers and value k that is chosen by Pari.

The second line contains n integers c1, c2, ..., cn (1 ≤ ci ≤ 1 000 000).

Output

Print "Yes" (without quotes) if Arya has a winning strategy independent of value of x, or "No" (without quotes) otherwise.

Examples

Input

4 5
2 3 5 12


Output

Yes


Input

2 7
2 3


Output

No

Note

In the first sample, Arya can understand <image> because 5 is one of the ancient numbers.

In the second sample, Arya can't be sure what <image> is. For example 1 and 7 have the same remainders after dividing by 2 and 3, but they differ in remainders after dividing by 7.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
long long gcd(long long x, long long y) {
  if (x < y) {
    long long t = x;
    x = y;
    y = t;
  }
  if (y == 0) return x;
  return gcd(y, x % y);
}
int main() {
  long long n, c, k, s, t, i, j;
  scanf("%I64d%I64d", &n, &k);
  t = 1;
  for (i = 1; i <= n; i++) {
    scanf("%I64d", &c);
    t = c * t / gcd(c, t);
    t = gcd(t, k);
  }
  if (t % k != 0 || (n == 1 && k == 2 && c == 1))
    printf("No\n");
  else
    printf("Yes\n");
  return 0;
}
