  Using $567\rm{pb}^{-1}$ of $e^+e^-$ collisions recorded at
$\sqrt{s}=4.599\rm{GeV}$ with the BESIII detector, we report first measurements
of absolute hadronic branching fractions of Cabibbo-favored decays of the
$\Lambda_{c}^{+}$ baryon with a double-tag technique. A global least-square
fitter is utilized to improve the measured precision. Among the measurements
for twelve $\Lambda_{c}^{+}$ decay modes, the branching fraction for
$\Lambda_{c}^{+} \rightarrow pK^-\pi^+$ is determined to be
$(5.84\pm0.27\pm0.23)\%$, where the first uncertainty is statistical and the
second is systematic. In addition, the measurements of the branching fractions
of the other eleven Cabbibo-favored hadronic decay modes are significantly
improved.
