To find out how many times an article has been cited when using Google Scholar, follow these steps:
Enter the article's title or keywords and author (if available) into the Search Bar. [NOTE: Google uses an implied AND, so there's no need to put AND between an article's title and an author's last name].
There will be a category under each result listing how many times that article has been cited in other sources (see the Screenshot for Step 2). The number of citing documents is hyperlinked and will take you to a list where you can see and potentially access the full text of those additional resources.
