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

```c
#include<stdio.h>
#include<math.h>
int main(){
  int n, x, t, a, b;
  scanf("%d %d %d ",&n, &x, &t);
 
  a = ceil((double)n / (double)x);
  b = a * t;
  printf("%d",b);
  return (0);
}  
    ```
