You and your dad go grocery shopping. The chocolatey Shmiff Bars that you and your three sisters like come in packages of six. How many packages should your dad buy to make sure that all four of you get an equal number of bars?
Answer: We need to find the least common multiple of 4 and 6. Since 12 is the LCM, your dad needs to buy 12 bars, or 2 packages. This way, each of you gets an equal number of Shmiff Bars, which is 3 bars.
