The lcm(M1,M2) function computes the element-wise least common multiple of M1 and M2.

If M1 is a scalar, then gcd computes least common multiple of M1 and each element of M2.

Arrays M1 and M2 must be the same size.

$\mathrm{M1}≔\mathrm{Matrix}\left(2\,3\,'\mathrm{fill}'=12x\right)\:$

$\mathrm{M2}≔\mathrm{Matrix}\left(2\,3\,'\mathrm{fill}'=27xy\right)\:$

$\mathrm{lcm}\left(\mathrm{M1}\,\mathrm{M2}\right)$
