To find the LCM, you first need to express the numbers as the product of their prime factors. In this case:

10z = 2x5xz

20x = 2x2x5xz

The next step is to identify the HCF. In this case that's 2x5xz = 10z. Then you multiply the numbers together and divide by the HCF:

10z x 20z/10z = 20z

Thus the LCM of 10z and 20z is 20z.
