Create column of common items from information in 4 columns

[Steve]

Can anyone tell me how to create a list of the common items that are
contained in 4 different columns?

For example:

I would like this:

2 1 3 1
4 4 4 3
5 5 6 4
6 6 7 6
8 9 9 9
9 10 9 10


To produce this in a column of its own:

4
6
9

The items listed in the column directly above are common to each of the
four columns....

Please help...

Try an array formula (press Ctrl Shift Enter when entering it). In E1
(assuming range you've given is in A1 to D6), paste in:
=IF(OR(A1=$B$1:$B$6),IF(OR(A1=$C$1:$C$6),IF(OR(A1=$D$1:$D$6),A1,""),""),"")
and press Ctrl Shift Enter which will be {} around the formula. Copy
this formula down to E6 and it should show 4, 6, 9 in the same row as
those numbers appear in column A.
I don't think it's a very elegant solution, and the results don't come
in consecutive rows, but it works.
