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 int gcd(long long int a, long long int b) {
  long long int r;
  if (a > b) {
    r = a % b;
    if (r == 0)
      return b;
    else
      return gcd(b, r);
  } else {
    r = b % a;
    if (r == 0)
      return a;
    else
      return gcd(a, r);
  }
}
int main() {
  long long int n, k;
  cin >> n >> k;
  long long int tmp = 1;
  int a;
  for (int i = 0; i < n; ++i) {
    scanf("%d", &a);
    a = gcd(a, k);
    tmp = (tmp * a) / gcd(tmp, a);
  }
  if (tmp == k) {
    cout << "Yes" << endl;
    return 0;
  } else {
    cout << "No" << endl;
    return 0;
  }
  return 0;
