In this work, we have studied a multi-lepton final state arising from sneutrino and left-handed slepton production at the high-luminosity and high-energy LHC in the context of R-parity violating supersymmetry when only the lepton number violating 
and/or 
couplings are non-zero. We have taken into account both pair production and associated production of the three generations of left-handed sleptons and sneutrinos, which are assumed to be mass degenerate. The lightest supersymmetric particle is assumed to be bino and it decays via the R-parity violating couplings into light leptons and neutrinos. Our final state has a large lepton multiplicity, 
. We perform both cut-based and machine learning-based analyses for comparison. We present our results in the bino-slepton/sneutrino mass plane in terms of exclusion and discovery reach at the LHC. Following our analysis, the slepton mass can be discovered up to 
1.54 TeV and excluded up to 1.87 TeV at the high-luminosity LHC, while these ranges go up to 2.46 and 3.06 TeV, respectively, at the high-energy LHC.
