If you have a version of Excel which supports worksheet functions SORTBY and UNIQUE you could do it with a couple of helper cells K3 and L3.
Two solutions in the attached, one at cell G7 which puts the results in 2 rows, sorted, the other at cell G10 which puts the results in a single row of cells, as you have, sorted.

If you don't have those functions available to you a pivot table is a very easy solution. See cell F14. Choose your number in cell G14. This also sorts.

I've added a few rows of raw data for testing, tweaked a few values in the raw data too. Cell J1 shows a list of numbers for testing.

It's interesting to note that the pivot table honours the difference between '121' and '0121' whereas the formulae lump these together.
