help with multiple unit pathfinding

Unity Engine

In my game you can select multiple units and send them to a destination with a mouse click. however when they try to go to the same place they all collide with each other and spin in circles. how can i make it so that when multiple units go to the same point they don’t try o pile on top of one another.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class ClickOn : MonoBehaviour {


    private MeshRenderer myRend;

    public bool currentlyIsSelected = false;
    //public bool ifCanMove = true;



    NavMeshAgent nav;
    Vector3 destination;
    Vector3 curPos;
   
    public GameObject HoverProjector;

    // Use this for initialization


    void Start () {
        myRend = GetComponent<MeshRenderer>();
        Camera.main.gameObject.GetComponent<Click>().selectableObjects.Add(this.gameObject);
        nav = GetComponent<NavMeshAgent>();
        //ifCanMove = true;
       
       
}
   
    // Update is called once per frame
    void Update () {
        if(currentlyIsSelected == true)
        {
            HoverProjector.SetActive(true);
            curPos = transform.position;

            if (Input.GetMouseButtonDown(0))
            {
                Move();
            }
        }
        else
        {
            HoverProjector.SetActive(false);
        }



    }

    public void ClickMe()
    {
        Debug.Log("I have been clicked");
    }

    public void Move()
    {


        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit, 100))
        {
            destination = hit.point;
            // nav.SetDestination(hit.point);
            nav.SetDestination(destination);


        }
    }



}
