## Abstract

We compute the strange quark mass [Formula Presented] and the average of the u and d quark masses [Formula Presented] using full lattice QCD with three dynamical quarks combined with the experimental values for the [Formula Presented] and K masses. The simulations have degenerate u and d quarks with masses [Formula Presented] as low as [Formula Presented] and two different values of the lattice spacing. The bare lattice quark masses obtained are converted to the [Formula Presented] scheme using perturbation theory at [Formula Presented] Our results are [Formula Presented] [Formula Presented] MeV, and [Formula Presented] where the errors are from statistics, simulation, perturbation theory, and electromagnetic effects, respectively.
