The first step would be to break down the numbers into their prime factors. In this case:
23 = 23
27 = 3x3x3
The next step would be to identify any common factors and discard them but as there are none, we simply use all the prime factors. Multiply them together to get the LCM:
3x3x3x23 = 621.
Thus the LCM of 23 and 27 is 621.
The LCM is: 621
LCM = 621 prime factorization of 23 = 23 27 = ------3 x 3 x 3 ============ LCM=23 x 3 x 3 x 3 = 621
