The lowest (or least) common multiple of 56 and 54 is 1,512 This can be found by collecting the least set of Prime number factors of both 54 and 56. The prime factors of 54 are (54 = 27 x 2 = 9 x 3 x 2 =) 3 x 3 x 3 x 2. The prime number factors of 56 are (56 = 28 x 2 = 14 x 2 x 2 =) 7 x 2 x 2 x 2 . The lowest common multiple can now be found by looking at both sets of prime number factors. 2 appears in both sets so we do not need to repeat in the answer, all other numbers are multiplied. The LCM is then 7 x 2 x 2 x 2 x 3 x 3 x 3 = 1,512
