  The simplest minimal subtraction method for massive {\lambda}{\phi}4 scalar
field theory is presented. We utilize the one-particle irreducible vertex parts
framework to deal only with the primitive divergent ones that can be
renormalized multiplicatively. We give a unified description for spacetime
metric tensor with either Minkowski or Euclidean signature.The partial-p
operation in the remaining diagrams of the two-point vertex part are used to
get rid of its overlapping divergences. We show how the parametric dissociation
transform effectively eliminates the external momentum dependence of the
coefficient of the squared bare mass after performing the partial-p operation
in the two-point vertex part diagrams. The resemblance of this method with a
minimal subtraction scheme in the massless theory is pointed out. We derive the
Callan-Symanzik equations using minimal subtraction arguments and discuss the
scaling limit in the ultraviolet region. We apply the method to determine
critical exponents for an O(N) internal symmetry at least up to two-loop order
with a flat Euclidean metric and find perfect agreement with all previous
results in the literature.
