the 2nd step is the C (common) part - finding the same (common) multiples from the number's given

There, you have written out some multiples off 6 and 4
danyaal
25 June 2012
looking back at the example we will see 12 and 24 is common in both multiples off 6 and 4
danyaal
25 June 2012
then the last part which also happens to be the easiest is looking for the lowest (L) from your list off common multiples
danyaal
25 June 2012
12 is the smaller than 24, so we will choose that one
