hi,
SET SERVEROUTPUT ON
DECLARE
    N NUMBER;
    I NUMBER;
    F NUMBER;
BEGIN
    N := &N;
    F := 1;
    FOR I IN 1 .. N
    LOOP
        F := F * I;
    END LOOP;
    DBMS_OUTPUT.PUT_LINE('THE FACTORIAL VALUE IS ' || F);
END;
/Tips:
1- post your code inside tags (start and end tag are the same) to proper formatting :)
2- use a meaningful name in the thread :)
