The product of two numbers is $1320$ and their $\text{H.C.F.}$ is $6$. The $\text{L.C.M.}$ of the numbers is:

For any two positive numbers, the relationship between their product, highest common factor ($\text{H.C.F.}$), and lowest common multiple ($\text{L.C.M.}$) is given by:
$$\text{Product of two numbers}=\text{H.C.F.}\times \text{L.C.M.}$$

Given values:

* $\text{Product}=1320$
* $\text{H.C.F.}=6$

Substituting these into the formula:

$$1320=6\times \text{L.C.M.}$$

$$\text{L.C.M.}=\frac{1320}{6}=220$$
