To find the LCM of 56 and 42, you first have to break them down into their prime factors: 56 = 2x2x2x7 42 = 2x3x7 The next step is to work out the HCF. In this case that will be 2x7 = 14. Finally, you multiply the numbers together and divide by the HCF. 56x42/14 = 168. Therefore the LCM of 56 and 42 is 168.
It is: 1680
LCM = 20,160
HCF = 56 LCM = 8008 616 = 2^3 x 7 x 11 728 = 2^3 x 7 x 13 hcf = 2^3 x 7 = 56 lcm = 2^3 x 7 x 11 x 13 = 8008
LCM is 20 and the hcf is 10
Least Common Multiple (LCM) for 64 56 80 is 2,240
HCF = 3... LCM = 18 !
