Example off a question
Find the LCM off 6 and 4
25 June 2012
6, 12, 18, 24, 30, 36,
4, 8, 12, 16, 20, 24, 28
25 June 2012
the 2nd step is the C (common) part - finding the same (common) multiples from the number's given
25 June 2012
There, you have written out some multiples off 6 and 4
25 June 2012
looking back at the example we will see 12 and 24 is common in both multiples off 6 and 4
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
25 June 2012
12 is the smaller than 24, so we will choose that one

Goodluck and all the best
