  The top quark mass is measured using $35.9~\mathrm{fb}^{-1}$ of LHC
proton-proton collision data collected with the CMS detector at
$\sqrt{s}=13~\mathrm{TeV}$ in 2016. The measurement uses the
$\mathrm{t}\overline{\mathrm{t}}$ all-jets final state, which comprises a total
of six jets. A kinematic fit is performed to reconstruct the decay of the
$\mathrm{t}\overline{\mathrm{t}}$ system and suppress QCD multijet background.
By means of the ideogram method, the top quark mass is determined,
simultaneously constraining an additional jet energy scale factor
($\text{JSF}$). The result of
$172.34\pm0.20\,\text{(stat+JSF)}\pm0.76\,\text{(syst)}~\mathrm{GeV}$ for the
top quark mass is in good agreement with previous measurements in the same and
different final states.
