Oh, isn't finding the greatest common factor like finding a happy little tree in a forest of numbers? Let's take a look at 40, 48, and 72. The greatest common factor for these numbers is 8, like a sturdy trunk supporting the branches of a tree. Just like in painting, finding the common factor helps bring harmony and balance to the numbers.
This is a terminology issue. 48 is not a factor of 8. 48 is a multiple of 8 and 8 is a factor of 48.
