Prime number indicator: in this activity, you will design a circuit that indicates whether a number between 0 through 15 is a prime number or not. a prime number is defined as a number that can be divided only by itself and 1. by definition, the numbers 0 and 1 are not prime. the circuit must have four binary inputs a, b, c, d, and one output, g. the output signal g is true (g = 1) if the input represents a prime number and is false (g = 0) otherwise.
