1. Sort all the files using SORT
2. Compare file1.txt and file2.txt using DIFF -- no contents were same, now merge these two files say new_file1.txt
3. Compare new_file1.txt with file3.txt as like above -- one content is matched so it will return the value as '6', use SED / AWK to remove that value from file3.txt and merge the remaining contents with new_file1.txt
4. Now finally, compare file4.txt with new_file1.txt -- no contents matched as per the example shown above.
You can try to code for above logic and still if you have doubts with the codes, provide your progress we can help you out.
This will work only if you're having limited no. of files, incase if you wanna to compare 40files then you will to try for various logic like using functions in shell scripting etc.

opendiff
opendiff(1) BSD General Commands Manual opendiff(1)NAME
opendiff -- Use FileMerge to graphically compare or merge file or directories
SYNOPSIS
opendiff file1 file2 [-ancestor ancestorFile] [-merge mergeFile]
opendiff dir1 dir2 [-ancestor ancestorDirectory] [-merge mergeDirectory]
DESCRIPTION
opendiff is a command line utility that provides a convenient way to launch the FileMerge application from Terminal to graphically compare
files or directories. If FileMerge is already running, opendiff will connect to that running instance for the new comparison. opendiff
exits immediately after the comparison request has been sent to FileMerge.
opendiff and FileMerge can be used to compare two files file1 and file2 or to compare two directories dir1 and dir2.
If the -ancestor flag is given, FileMerge will compare the two files or directories to a common ancestor. This is useful if two people inde-
pendently modify copies of a single original file or directory.
FileMerge lets you merge two files or directories together to create a third file or directory. To see the contents of a merged file, drag
the splitter bar at the bottom of FileMerge's file comparison window. The contents of the merged file can be directly edited within File-
Merge. After editing, the merged file can be saved to the file (or into the directory) specified with the Fl merge flag. If a destination
is not specified with the -merge flag, FileMerge will ask for a destination file or directory when you try to save a merged file.
For further information, please consult the Help information available from the FileMerge application.
