Find the LCM

35b^4c^5,7b^4c^4,10b^9c^3

Would the answer be 70?

  • Algebra -

    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.

    I am stumped by these two LCM questions for some reason. Find The LCM for #1 2(R-7) and 14(R-7) #2 (1+4r), (1-16r^2), and (1-4r) It seems like #1 is already at the LCM and #2 would be (1+4r)(1-4r) Am I even vaguely correct?
