How does the LCM help you figure out the fewest hot dogs and buns to buy so they come out even?¿Cómo te ayuda el mínimo común múltiplo a averiguar la menor cantidad de salchichas y panes que hay que comprar para que salgan parejos?

Model: The next shared check is a common multiple of 4 and 6, not their sum. — Students reason that each astronaut repeats on multiples of their own number, so they only overlap at a common multiple, and adding 4 + 6 does not land on both schedules.
