This interactive PowerPoint game has students choosing the correct GCF (Greatest Common Factor) or the LCM (Least Common Multiple) of a set of numbers.
Four-In-A-Row is great to use with pairs of students on an individual computer or on a interactive board for the whole class.
Many slides have both the GCF and the LCM listed requiring students to carefully chose. Many students confuse LCM and GCF so playing this game as a class gives another opportunity to have discussions about the difference in each.

The design choice of putting both the GCF and the LCM on many slides is the real gem here — students who confuse the two have to slow down and actually distinguish them, not just compute. Using it with pairs on individual computers sounds ideal for the discussion-heavy approach you describe, where each round becomes a conversation about the difference between the two. The bonus round idea of asking which answer is which could also make a great follow-up assessment. I run factorcalculator.org, a free tool students can use to quickly check GCF and LCM values as they practice, which pairs well with a game like this.
