Greatest Common Factors and Least Common Multiples

What is a factor? What is a multiple?

Have you ever had a box of chocolates, and you tell yourself that you'll just have each day? That way, if there are 12 chocolates, you can make them last days ๐.
But, self-control is hard, so maybe instead you'll have a day and make them last days. Or, honestly, just have in day. Tomorrow's a new day โ๏ธ.

These are factor pairs! We can get to 12 in three different ways:

So, the factors of 12 are .
On the other hand, if we wanted to buy more boxes of chocolates, we could buy 1 box ( chocolates), 2 boxes ( chocolates), 3 boxes ( chocolates), and so on.
So, the multiples of 12 are

Notice, we can keep adding 12 to get more multiples, but we can't get more factors. To remember the difference, just think more multiples and few factors!
