I want beamer to automatically split my text over multiple frames (as many as is required) while retaining the format of the specified number of multicolumns (in this case 3). I do not want to have to specify the column width that is why i have used "multicols." I found the question entitled Allow theorem split in many frames in beamer but this question is unique to the multicol environment.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

How much of the frame structure do you need?

This for example more or less works

%begin{frame}[allowframebreaks]{Example Frame}

  begin{multicols}{3}[Example Frame] 

.....

end{multicols}

%end{frame}

In that it makes something that looks like a two slide presentation with three columns on each slide and a title on the first page. But it isn't a frame to beamer, so its interaction with other beamer features will be different.
