C# code structure question

As an example, i have 2 classes, both doing almost the same stuff:

 public class PlayerManager : MonoBehaviour
 {
     void Update()
     {
         RaycastHit hit;
         if (Input.GetMouseButtonDown(0))
         {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             if (Physics.Raycast(ray, out hit))
                 Move(hit.point);
         }
     }
 
     public void Move(Vector3 position)
     {
         // Move to given position
     }
 }
 
 public class NpcManager : MonoBehaviour
 {
     void Update()
     {
         RaycastHit hit;
         if (Input.GetMouseButtonDown(0))
         {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             if (Physics.Raycast(ray, out hit))
                 Move(hit.point);
         }
     }
 
     public void Move(Vector3 position)
     {
         // Move to given position
     }
 }

Instead of detecting mouse click and finding hit.point in both classes Update, i'd like to move that code to a third class, which would then call the Move method of PlayerManager and NpcManager.

Of course i could require both scripts via GetComponent or other ways, but as my classes grow this becomes quickly unmantainable.

Any suggestions on how can i do this in a way that is mantainable even when expanding the codebase?
