LCM問題

(p^2)q(p+q) ,(p^3)q and p(p+q)^2
L.C.M.=(p^3)(q)(p+q)^2

p^2 q (p+q) = (q) (p^2) (p+q)

p^3 q = (q) (p^2) (p)

p (p+q)^2= (p+q) (p+q) (p)

we have to find the common of them,
therefore, the LCM of them is
(q) (p^2) (p+q) (p) (p+q) = (p^3) (p+q)2 (q)

i hope it can help . cheers

i'm sorry for the typing error, eventally, the answer should be(p^3) (p q)^2 (q) not (p^3) (p q)2 (q) , there is a ^ stand for square is missing. sorry.
