Answer:
720
Explanation:
To find the LCM (Least Common Multiple) of 180 and 240, we need to list out the multiples of each number until we find the smallest multiple that they have in common.
Multiples of 180: 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, 1980, 2160, 2340, 2520, 2700, 2880, 3060, 3240, 3420, 3600...
Multiples of 240: 240, 480, 720, 960, 1200, 1440, 1680, 1920, 2160, 2400, 2640, 2880, 3120, 3360, 3600...
From the above lists, we can see that the smallest multiple that both 180 and 240 have in common is 720. Therefore, the LCM of 180 and 240 is 720.
