One AND gate for AB, one AND gate to combine AB & C, one NOT gate for C', then one AND gate for AC', and then OR gate for ABC & AB, another OR gate to combine AC'. So there is need of 2 OR gate.

If we will simplify this it will come AB+AC'. This means that we require 2 and gates and one not gate and to combine the output of 2 and gates one or gate. So, 2And + 1Not + 1OR.

AB=1 AND gate.
ABC=1 AND gate (get AB from output above then and to C),
AC=1 AND gate,
C'=1 NOT gate,
ABC+ AB+ AC'= 1 OR GATE(3 INPUT GATE).

Three AND gates and one OR gate. Suppose consider NOT gate made up of AND logic.

Three and gates two or gate one not gate.
