Well, last night I got stumped by my 6th grader’s homework. Wondering if any of you less math-challenged folk out there could help me out.

Apparently they are studying factoring, and this particular assignment concerned greatest common factors (GCF) and lowest common multiples (LCM). In one section you were to find the pair of numbers that shared the specified attributes. The first question specified LCM = 35, GCF = 7.

Am I wrong in thinking that those were the pair of numbers requested? The LCM of 7 and 35 = 35, and the GCF of 7 and 35 = 7.

Seemed like the same was true for the other 2 sets of criteria. I remember one was GCF = 10, LCM = 120. Can’t remember the other set. I remember the GCF was 1, and think the LCM may have been 60.

Seemed kinda - um - stupid. *Dammit, Jim! I’m a LAWYER, not a mathemetician!*

I could only guess that this was an attempt to present these concepts in a different manner, which might enlighten those kids that did not grasp the more common presentations.

Any thoughts?
