How do you get the LCM of 6 and 16?

Answer 1

First you split both numbers into their prime factors:

6 = 2x3

16 = 2x2x2x2

The next step is to identify the HCF. In this case the HCF is 2. Finally you multiply the numbers together and divide by the HCF:

6x16/2 = 48

And so the LCM of 6 and 16 is 48.
