Problem Statement

Having learned the multiplication table, Takahashi can multiply two integers between 1 and 9 (inclusive) together.

Given an integer N, determine whether N can be represented as the product of two integers between 1 and 9. If it can, print Yes; if it cannot, print No.

Constraints

1 \leq N \leq 100

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N can be represented as the product of two integers between 1 and 9 (inclusive), print Yes; if it cannot, print No.

Sample Input 1

10

Sample Output 1

Yes

10 can be represented as, for example, 2 \times 5.

Sample Input 2

50

Sample Output 2

No

50 cannot be represented as the product of two integers between 1 and 9.

Sample Input 3

81

Sample Output 3

Yes

# ABC144b


def main():
    import sys
    input = sys.stdin.readline
    sys.setrecursionlimit(10**6)

    # map(int,input().split())

    n = int(input())
    for i in range(1, 10):
        if n % i != 0:
            continue
        for j in range(1, 10):
            if n//i % j != 0:
                continue
            if 0 <= n//i//j <= 1:
                print('Yes')
                exit(0)
    print('No')
