The GCF is 1.
The LCM is: 243
THe LCM of 123 and 243 is 9963 The first step in working out the least common multiple of two numbers is to express them as their prime factors. In this case 123 and 243 can be broken down as follows: 123 = 41x3 243 = 3x3x3x3x3 The next step is to identify and discard the duplicates of any common factors. In this case, both numbers have a 3 as a prime factor, so we can discard one of these. Take all the other prime factors (41, 3, 3, 3, 3 and 3) and multiply them together to get the LCM: 41x3x3x3x3x3=9963
The LCM is 9471.
Since 615 is a multiple of 123, it is automatically the LCM.
The LCM is 1330.
