Here, I will recommend you to do following things:
- you can add those urls into Robots.txt file and disallow them to get crawled by any of the bots.
- second thing you can do is to add redirect 301 to those pages who are showing 404 error on search results.
- Thirdly, you can send those url's list to GWT to Disavow and request to remove from search engine results.
Hope, this will help you.
