Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76 etc. and the multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, ... Common multiples of 4 and 6 are simply the numbers that are in both lists: 12, 24, 36, 48, 60, 72, .... So the least common multiple of 4 and 6 is the smallest one of those: 12
