To find the LCM you first need to break the numbers down into their prime factors:
32 = 2x2x2x2x2
12 = 2x2x3
Next, you identify any common factors, and cross off the duplicates. In this case both numbers have two 2s as prime factors. That leaves us with 2, 2, 2, 2, 2 and 3. Multiplying these together gives 96.
Therefore the LCM of 32 and 12 is 96.
