What is the least common multiple of 4 10 and 15?

Well, isn't that just a happy little math problem! To find the least common multiple of 4, 10, and 15, we first list the multiples of each number: 4 (4, 8, 12, 16, 20...), 10 (10, 20, 30...), and 15 (15, 30, 45...). Then, we look for the smallest number that appears in all three lists, which in this case is 60. So, the least common multiple of 4, 10, and 15 is 60. Happy calculating!
