  We determine the geometrical and viewing angle parameters of the Large
Magellanic Cloud (LMC) using the Leavitt law based on a sample of more than
$3500$ common classical Cepheids (FU and FO) in optical ($V,I$), near-infrared
($JHK_{s}$) and mid-infrared ($[3.6]~\mu$m and $[4.5]~\mu$m) photometric bands.
Statistical reddening and distance modulus free from the effect of reddening to
each of the individual Cepheids are obtained using the simultaneous multi-band
fit to the apparent distance moduli from the analysis of the resulting Leavitt
laws in these seven photometric bands. A reddening map of the LMC obtained from
the analysis shows good agreement with the other maps available in the
literature. Extinction free distance measurements along with the information of
the equatorial coordinates $(\alpha,\delta)$ for individual stars are used to
obtain the corresponding Cartesian coordinates with respect to the plane of the
sky. By fitting a plane solution of the form $z=f(x,y)$ to the observed three
dimensional distribution, the following viewing angle parameters of the LMC are
obtained: inclination angle $i=25^{\circ}.110\pm 0^{\circ}.365$, position angle
of line of nodes $\theta_{\text{lon}}=154^{\circ}.702\pm1^{\circ}.378$. On the
other hand, modelling the observed three dimensional distribution of the
Cepheids as a triaxial ellipsoid, the following values of the geometrical axes
ratios of the LMC are obtained: $1.000\pm 0.003:1.151\pm0.003:1.890\pm 0.014$
with the viewing angle parameters: inclination angle of $i=11^{\circ}.920\pm
0^{\circ}.315$ with respect to the longest axis from the line of sight and
position angle of line of nodes $\theta_{\rm lon} = 128^{\circ}.871\pm
0^{\circ}.569$. The position angles are measured eastwards from north.
