What is the least common multiple of 6 and 10 ? A 60

To find the least common multiple (LCM) of 6 and 10, you can list the multiples of both numbers. The multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and for 10, they are 10, 20, 30, 40, 50, 60. The smallest common multiple in both lists is 30, so the least common multiple of 6 and 10 is actually 30, not 60! A common mistake is assuming LCM is simply the product of the two numbers. While multiplying gives you the highest possible overlap, the LCM is about finding the smallest shared multiple. Always factor both numbers to see how they overlap!
