I am stumped by these two LCM questions for some reason. Find The LCM for #1 2(R7) and 14(R7) #2 (1+4r), (116r^2), and (14r) It seems like #1 is already at the LCM and #2 would be (1+4r)(14r) Am I even vaguely correct? Thanks

have the answer and would love confirmation. VERY APPRECIATED! Find the LCM OF (1+2t), (14t^2), and (12t). 14t^2=(1+2t)(12t) 1+2t = 1+2t 14t^2= (1+2t)(12t) 12t = 1  2t. The LCM for all numbers is 14t^2 = (1+2t)(12t)
