A8341. Lucky Division

编程题 普及/提高-

题目描述

Petya loves lucky numbers. Everybody knows that lucky numbers are positive integers whose decimal representation contains only the lucky digits 4 and 7. For example, numbers 47, 744, 4 are lucky and 5, 17, 467 are not.

Petya calls a number almost lucky if it could be evenly divided by some lucky number. Help him find out if the given number $n$ is almost lucky.

输入格式

The single line contains an integer $n$ $(1<=n<=1000)$ — the number that needs to be checked.

输出格式

In the only line print "YES" (without the quotes), if number $n$ is almost lucky. Otherwise, print "NO" (without the quotes).

输入输出样例

说明/提示
