24 = 2 X 2 X 2 X 3 24 = 2 X 2 X 2 X 3
36 = 2 X 2 X 3 X 3 36 = 2 X 2 X 3 X 3
48 = 2 X 2 X 2 X 3 X 2 48 = 2 X 2 X 2 X 3 X 2
2 X 2 X 3 = 12 2 X 2 X 2 X 3 X 3 X 2 = 144
Factor = breaking down; you are looking
for a number equal to or smaller than the
lowest number in the group.
Multiple = increasing/larger; the LCM will be
equal to the largest number in the group or
larger
than all the numbers.
