There’s a wide range of uses.

You can use them as part of the math for optimizing something. This is *huge* in various business processes, engineering, and programming, because optimizing a process means cutting off excess and gaining efficiency.

Like, let’s say your business makes spare wheels. Each tire needs a metal wheel and a rubber tire. Wheels are bought in packs of 6, tires in packs of 8. Using LCM, you determine that the least number of spares you could make without buying too many of either component is 24 – 4 packs of wheels, 6 packs of tires. Buying in that way, you save money on excess parts, and space in your inventory for products that are incomplete and thus can’t be shipped.
