To find the LCM you first have to break the numbers into their prime factors: 60 = 2x2x3x5 100 = 2x2x5x5 The next step is to identify the HCF. In this case it's 2x2x5 = 20. Finally, you multiply the numbers together and divide by the HCF: 60x100/20 = 300 Therefore the LCM of 60 and 100 is 300.
The easiest way to do this is to split the numbers down into their prime factors: 14 = 2x7 20 = 2x2x5 The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore, the HCF of 14 and 20 is 2.
