To find the LCM of 110 and 20, you first need to break them up into their prime factors:
110 = 2x5x11
20 = 2x2x5
The next step is to identify the HCF. In this case the HCF will be 2x5 = 10. To find the LCM you multiply the numbers together and divide by the HCF:
110x20/10 = 220.
Thus the LCM of 110 and 20 is 220.
