Find the greatest common factor of the followig monomials 21u^5v,3u^4v^6, and 3u^2v^5

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
