Factor Rainbow or Tree?

A factor rainbow can be helpful. A factor tree can also be helpful. However, when is the factor rainbow better than the tree? This was the question I am required to answer from math class. Sometimes, A factor tree can really help with GCF ( greatest common factor) and LCM (least common multiples) in math, but tell me, does it help find ALL factors of a number?

With a factor tree though, you won't get as many factors and you will take much longer. When you are supposed to find all the factors of one number, that is the time to use a factor rainbow.

I mean if I get too sleepy in the mornings, I might lag behind in class and not pay much attention. That would be bad. Also, I don't get ...

Picture this, at 8:00 A.M. in the morning, after late night party, you are dragged out of bed expected to walk around and flip on some bars with your hands for a WORLD WIDE CHAMPIONSHIP that you forgot about. One more thing to go with this, ever heard the term " If you fall of the horse, the only thing to do is get back on"? I would love it if you understood WHAT gets you back on the horse. I mean, if nothing did, the horse would stroll away leaving you behind. How? Presenting my independent narrative writing piece with only a few pinches of help! Just read on!
