Factorial 4,24 is consequence of Prolog program as there is a clause tree rooted and all of the root nodes are true, whereas literal factorial 5,6 , on the other hand, is not at all a consequence of prolog program as there is no clause tree rooted for 5,6 and hence it gives false. We have seen what Prolog factorial and its definition is. We have gone through how Prolog word came from and what is the Prolog programming all about. We have seen a few of the examples too which give us the factorial of any non-negative integer.
We have also depicted an example of 4! This is a guide to Prolog Factorial. Here we discuss the introduction, logic behind prolog, and examples for better understanding.

See this answer — false. Add a comment. Active Oldest Votes. You do it the usual Prolog way - by defining a recursive rule that covers two clauses: When the number is 0 , its factorial is 1 - This can be done with a simple fact. Moreover, since all CLP FD constraints always terminate , placing them earlier can at most improve , never worsen, the termination properties of your programs. In the case above, the clauses are mutually exclusive if the first argument is sufficiently instantiated.
