Remove duplicates from multiple variable

Hello, 

I would like to ask if there is any function that can remove Duplicates from multiple variable

For example: 

20

20

30

30

30

10

The result of this should be: 

20

30

10

In this case union will not work for me because I don't have another array to which I cam compare.
