This is really the “Week of the LCM” for me.
Just as I was finishing my last post, on a new way to find the LCM for a pair of numbers, I discovered another way to do the same thing.
I was looking at the problems at the end of my last post, these problems:
b) 15 and 20; LCM = 60
c) 18 and 20; LCM = 180
d) 24 and 28; LCM = 168, ….
… when I noticed something.
