  In this work, we discuss the determination of the distance to the Large
Magellanic Cloud (LMC) using the Leavitt Law, utilizing the public catalog of
Classical Cepheid Variable stars from the observational project OGLE-IV (The
Optical Gravitational Lensing Experiment Collection of Variable Stars),
consisting of 4709 stars in the Large Magellanic Cloud. To determine the
pulsation period of Cepheid Variable stars, we employ the computational
algorithm \textit{Lomb-Scargle periodogram} modified for our data.
Additionally, with the calculation of the period, we can derive a
period-luminosity relation for Cepheid Variables in the Large Magellanic Cloud
and, using an independent calibration distance, deduce their distance moduli.
We also discuss some general theoretical concepts of the physical mechanism
behind the oscillation of variable stars.
