+w%5E3%2B4w%5E2%2B4w+=+w%28w%5E2+%2B+4w+%2B+4%29+=+w%28w%2B2%29%5E2
w%5E2+-+4w+=+w%28w-4%29
Therefore LCM = w%28w%2B2%29%5E2%28w-4%29

Find the LCM
Factor each expression:
w^3+4w^2+4w
w(w^2+4w+4)
w(w+2)^2
----------------
w^2-4w
w(w-4)
================
The lcm must have each factor in its highest power:
LCM = w(w-4)(w+2)^2
========================
