At Howard High School, the football team and the lacrosse team both had a game today. The football team has a game every 7 days, and the lacrosse team has a game every 4 days. In how many days will they both have a game on the same day again?(1 point)
To find the number of days they will both have a game on the same day again, we need to find the least common multiple (LCM) of 7 and 4.
Prime factors of 7: 7
Prime factors of 4: 2, 2
To find the LCM, we take the highest power of each prime factor that appears in either number: 7 * 2 * 2 = 28.
Therefore, it will take 28 days for both teams to have a game on the same day again. Answer: \boxed{28}.
