When calculating the LCM of two numbers, you first need to split them into their prime factors. In this case we get:

174 = 2x3x29

448 = 2x2x2x2x2x2x7

The next step is to identify any common factors. In this case both numbers have 2 as a common prime factor, so we can cross off the duplicate. That leaves 2, 2, 2, 2, 2, 2, 3, 7 and 29. Multiplying these together gives 38,976.

Therefore the LCM of 174 and 448 is 38,976
