Find the LCM
35b^4c^5,7b^4c^4,10b^9c^3
Would the answer be 70?

The LCM is always equal to or greater than(=>) the greatest coefficient.
In this case, the greatest coefficient
is 35. 35 will work only if it is
divisible by all of the other coefficients. 35 is not divisible by 10. Therefore, it does not meet both
requirements. So we try 2*35(70). It meets both requirements. If 70 had not
met both requirements, we would have
tried 3*35 and so on. 
Thank you very much...

I 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) Thank …

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?
