status 419 for Update in laravel ajax

I am getting a error as 419, for my update function. Something is not working properly; here is my ajax function in index.blade.php

   $('#action1').click(function (){
               var Ids = new Array();
               var Names = new Array();
               var Status = new Array();
               if($(".selected").length){
                $(".selected").each(function(){
                  Ids.push($(this).children(".id").html());
                  Names.push($(this).children(".company_name").html());
                  Status.push($(this).children(".status").html());
                });
                $.ajax({
                  url: 'update',
                  method:'POST',
                  dataType: 'json',
                  "id":Ids,
                  "company_name":Names,
                  "status":Status,
                  success: function(data){
                    $('#form1').html(data.success);
                  }
                  });
                // alert(Ids);
                // alert(Names);
                // alert(Status);

               }else{
                alert("No row is selected.");
               }
            });

and this is my controller file:

 public function update(Request $request)
{
    $ids = $request->input('Ids');
    $success_output = '';
      $companies = companies::find($ids);
      companies::whereIn('id',$ids);
      $this->validate($request,
        ['company_name' => 'required',
            'status' => 'required',
        ]);
      $companies->company_name = $request->Names;
      $companies->status = $request->Status;
      $companies->save();
      $success_output = '<div class="alert alert-success">Data Inserted</div>';

        $output = array(
                'errror' => $error_array,
                'success' => $success_output
            );
            echo json_encode($output);
      return redirect('/companies')->with('success','updated');
}

and this is my route function:

Route::post('update','AjaxController@update');

I want to update multiple rows at a time, but the update function may not working. can anyone suggest any solution?
