Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include <stdio.h>

int main(){

    long long  m;
    long long k,n;
    m=0;
    n=0;
    scanf("%lld",&k);
    if(k%2==0||k%5==0){
        n=-1;
        printf("%lld",n);
        return 0;
    }
    else
    {
    while(1){
        m=(m*10+7)%k;
        n+=1;
        if(m %k  ==0){

            printf("%lld",n);
            return 0;
        }
    }
    }
    /*return EXIT_SUCCESS;*/
