user: I've been tracking the stock market and I'm interested in Apple's performance, but I only remember the ticker symbol 'AAPL', not the full company name. Could you look that up for me? Additionally, I need to schedule some events and I want them to sync up. The first event is every 12 days and the second one every 18 days. I need to know the least common multiple to find out when they will coincide. Lastly, I'm planning a triangular garden bed; it's going to have a 10-unit base and rise up 15 units in height. I need to calculate how much area that will cover.
