arrange 3,4and 5 inside your"cake"
ask your self do 3,4 and 5 have any common factors
if not factor out one of the numbers
OBJECTIVE IS TO GET ALL NUMBERS TO 1 and multiply all factors once they do
so
3 goes into 3 once
3 goes into 4 0 times
and 3 goes into 5 0 times
next take 4 and do the same
take 5 and do the same as well
the factors u should be left with are 3,4,5

3*4*5=60
lcm=60
