How to quickly extract a unique list of rows from a cell array?

So, I have an unacceptably large cell array, with far too many rows to reasonably display, and only 5 columns.

Each column contains a different format (some string, some numeric).

I know that many of the rows of the array are duplicated, so what I would like to do is to quickly and simply remove these duplicates.

Has anyone got a quick way of achieving this?

 Array = {45 654 9841 'ra' 'rb';
          45 684 9841 'ra' 'rb';
          ...
          45 654 9841 'ra' 'rb';
          45 684 9842 'ra' 'rb';
          1  651 91   'ra' 'ra';

[idx,idx]=unique(cell2mat([cellfun(@num2str,A(:,1:3),'un',0) A(:,4:5)]),'rows')
out=A(idx,:)

Doesn't work due to the fact my numbers vary in magnitude by more than 10 times.
