To find the LCM of two numbers, you first need to break those numbers down into their prime factors. For 42 and 54, this can be done as follows:
42 = 2x3x7
54 = 2x3x3x3
The next step is to identify any common factors. In this case, there are common prime factors of 2 and 3, which means one of each can be discarded. Take every other prime factor (7, 2, 3, 3 and 3) and multiply them together to get the LCM:
7x2x3x3x3=378
Thus the lowest common multiple of 42 and 54 is 378.
