I have below function which returns a value based on the input. I need to make this code as fast as possible, without using divison or modulo operator or loops. 
Each consecutive value is separated by amount almost equal to 6553. 

```
int GetScalingFactor(int input)
{
    unsigned int factor = 0;

    if(input < 13107) factor = 72816;
    else if(input < 19660) factor = 81918;
    else if(input < 26214) factor = 93621;
    else if(input < 32767) factor = 109225;
    else if(input < 39321) factor = 131070;
    else if(input < 45874) factor = 163837;
    else if(input < 52428) factor = 218450;
    else if(input < 58981) factor = 327675;

    return factor;
}

```
