$93 z^{3}$ $93z^3$

Explanation:

LCM means the least number which is divisible by both $31 z^{3} and 93 z^{2}$ $31z^3 and 93z^2$ . It is obviuosly $93 z^{3}$ $93z^3$ , but it can be determined by factorisation method easily

$31 z^{3} = 31 \cdot z \cdot z \cdot z$ $31z^3 = 31*z*z*z$
$91 z^{2} = 31 \cdot 3 \cdot z \cdot z$ $91z^2 =31*3*z*z$

First pick up the common factors 31zz and multiply the remaining numbers z*3 with this.

This makes up $31 \cdot z \cdot z \cdot 3 \cdot z = 93 z^{3}$ $31*z*z*3*z = 93 z^3$

$93 z^{3}$ $93z^3$

Explanation:

The LCM (Least Common Multiple) is the smallest value which each of two (or more) values divide evenly into.

Dividing $31 z^{2}$ $31z^2$ and $93 z^{3}$ $93z^3$ into factors and selecting all factors that are required by at least one of the two values:
${:(31z^3," = ", ,31, z, z, z), (93z^2," = ",3,31, z,z, ),("required factors:", ,3, 31, z, z, z) :}$

The required factors of the LCM of $31z^3$ and $93z^2$ are
$3xx31xxzxxzxxz$

$rArr LCM(31z^3,93z^2) = 93z^3$
