description: Based on 4.5 fb$^{-1}$ data taken at seven center-of-mass energies ranging from 4.600 to 4.699 GeV with the BESIII detector at the BEPCII collider, we measure the branching fractions of $Λ_{c}^{+}\rightarrowΣ^{+}+hadrons$ relative to $Λ_{c}^{+}\rightarrow Σ^+ π^+ π^-$. Combining with the world average branching fraction of $Λ_{c}^{+}\rightarrow Σ^+ π^+ π^-$, their branching fractions are measured to be $(0.377\pm0.042\pm0.018\pm0.021)\%$ for $Λ_{c}^{+}\rightarrowΣ^{+} K^{+} K^{-}$, $(0.200\pm0.023\pm0.010\pm0.011)\%$ for $Λ_{c}^{+}\rightarrowΣ^{+} K^{+} π^{-}$, $(0.414\pm0.080\pm0.029\pm0.023)\%$ for $Λ_{c}^{+}\rightarrowΣ^{+}ϕ$ and $(0.197\pm0.036\pm0.008\pm0.011)\%$ for $Λ_{c}^{+}\rightarrowΣ^{+}K^{+} K^{-}$(non-$ϕ$). In all the above results, the first uncertainties are statistical, the second are systematic and the third are from external input of the branching fraction of $Λ_{c}^{+}\rightarrow Σ^+ π^+ π^-$. Since no signal for $Λ_{c}^{+}\rightarrowΣ^{+} K^{+} π^{-}π^{0}$ is observed, the upper limit of its branching fraction is determined to be 0.11\% at the 90$\%$ confidence level.
