How to Identify, How many layouts present in the web site

How to identify number of layouts present in the entire web site with above 1 laks pages.

I don't really understand the question, probably because you haven't given us enough information to even guess at possible answers.

So, here's my answer: Find the person who created all of the layouts, and ask him/her how many of them he created.

Sample Site Site contain so many pages, nearly 1 lak. Those pages layouts are like attached images, now
