  In this article, we deal with how to distinguish the signatures of different
\LQs at the LHC/FCC if all of them lie within similar mass and coupling range
and can be produced at present and future colliders. It has been found that
hard scattering cross-sections and angular distributions can be used to
differentiate scalar and vector Leptoquarks. On the other hand, final state
topology and determination of jet charge can separate \LQs with same spin even
from same $SU(2)_L$ multiplet. We performed a PYTHIA8 based analysis
considering all the dominant Standard Model (SM) backgrounds at the LHC/FCC
with centre of mass energies of 14, 27 and 100 TeV for scalar ($S_1$) and
vector ($\widetilde{U}_{1\mu}$) Leptoquarks. We see that confirming evidence of
scalar Leptoquark at 14 TeV requires 1000 fb$^{-1}$ of integrated luminosity,
whereas the vector Leptoquark can be probed with very early data. But, at 100
TeV with 1000 fb$^{-1}$ of integrated luminosity, scalar Leptoquark of mass 3.5
TeV and vector Leptoquark of mass more than 5 TeV can be probed easily.
