description: We report measurements of the branching fractions of the decays $Λ^+_c\toΣ^+π^-π^+$, $Λ^+_c\toΣ^0π^+π^0$ and $Λ^+_c\toΣ^+π^0π^0$ relative to the reference channel $Λ^+_c\to pK^-π^+$. The analysis is based on the full data sample collected at and close to $Υ(4S)$ resonance by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider corresponding to the integrated luminosity of 711 fb$^{-1}$. We measure ${\cal B}(Λ^+_c\rightarrowΣ^+π^-π^+)/{\cal B}(Λ^+_c\to pK^-π^+) = 0.706~\pm 0.003~\pm 0.029$, ${\cal B}(Λ^+_c\rightarrowΣ^0π^+π^0)/{\cal B}(Λ^+_c\to pK^-π^+) = 0.491~\pm 0.005~\pm 0.028$ and ${\cal B}(Λ^+_c\rightarrowΣ^+π^0π^0)/{\cal B}(Λ^+_c\to pK^-π^+) = 0.198~\pm 0.006~\pm 0.016$. The listed uncertainties are statistical and systematic, respectively.
