How do you get the LCM of 56 and 42?

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.
