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

```c
main(){
    int k;
    scanf("%d",&k);
    int su=0;
    for(int i=1;i<=k;i++){
        su=(su*10+7)%k;
        
        if(su%k==0){
            printf("%d",i);
            return 0;
        }
    }
    printf("-1");
}```
