What is a composite numbers 93A 67B 47C or 31D?

93 is a composite number, so 93A should be a composite number if A is an integer. 67B would be a composite number if B is an integer greater than 1. 47C would be a composite number if C is an integer greater than 1. 31D would be a composite number if D is an integer greater than 1. Any number that can be produced by multiplying two integers greater than 1 together will be a composite number. So, 67 x B would be a composite number, even though 67 itself is prime.
