We compute the leading, strong-interaction contribution to the anomalous magnetic moment of the electron, muon, and tau using lattice quantum chromodynamics (QCD) simulations. Calculations include the effects of u, d, s, and c quarks and are performed directly at the physical values of the quark masses and in volumes of linear extent larger than 6 fm. All connected and disconnected Wick contractions are calculated. Continuum limits are carried out using six lattice spacings. We obtain a(e)(LO-HVP) = 189.3(2.6)(5.6) x 10(-14), a(mu)(LO-HVP) = 711.1(7.5)(17.4) x 10(-10) and a(tau)(LO-HVP) = 341.0(0.8)(3.2) x 10(-8), where the first error is statistical and the second is systematic.
