$$\left(a \vee b\right) \wedge \left(a \vee c\right) \wedge \left(b \vee c\right) = \left(a \wedge b\right) \vee \left(a \wedge c\right) \vee \left(b \wedge c\right)$$
$$\left(\left(a \vee b\right) \wedge \left(a \vee c\right) \wedge \left(b \vee c\right)\right) \Rightarrow \left(a \wedge b \wedge c\right) = \left(\neg a \wedge \neg b\right) \vee \left(\neg a \wedge \neg c\right) \vee \left(\neg b \wedge \neg c\right) \vee \left(a \wedge b \wedge c\right)$$
