Hi Ken,
Is the content actually exactly the same but running on different domains? That will determine how to approach this issue. If all the the content is the same you can either utilize 301 redirects or rel=canonical tags to help the engines view the multiple sites as a single site and combine any link juice that's associated with each of the 50 sites. If the content isn't actually duplicitous then it or the page titles are extremely similar. In the long run I would recommend localizing your content so as to not only help from an SEO perspective but to also improve the user experience and hopefully the conversion rates as well.
