  Recent radio observations have obtained stringent constraints for
annihilating dark matter. In this article, we use the radio continuum spectral
data of the Large Magellanic Cloud (LMC) to analyze the dark matter
annihilation signals. We have discovered a slightly positive signal of dark
matter annihilation with a $1.5\sigma$ statistical significance. The overall
best-fit dark matter mass is $m_{\rm DM} \approx 90$ GeV, annihilating via
$b\bar{b}$ channel. We have also constrained the $3\sigma$ lower limits of dark
matter mass with the standard thermal dark matter annihilation cross section
for the $e^+e^-$, $\mu^+\mu^-$, $\tau^+\tau^-$ and $b\bar{b}$ channels.
