A multiple of a number is the product of that number and any whole number. For example, the multiples of four are 4, 8, 12, 16, 20, etc. If we want to find a least common multiple for two numbers, we are looking for the first number in the list that they have in common. Sometimes the LCM will be the product of the two given numbers (like the LCM of 5 and 8 is 40), but sometimes it will be something smaller (like the LCM of 6 and 8 is 24, not their product, 48).
