The use of calculator is not permitted. The Boulevard Hotel has a peculiar way of numbering its rooms. The first room on each floor is numbered as the product of all floor number below it starting from floor number on ( the ground floor is not counted). For example , the first room on the fourth floor would be numbered as 1 xx 2 xx 3 = 6 . All successive room numbers would be numbered three more than the previous room number. Thus , on the fourth floor, rooms are numbered as 6,6+3 = 9,6 + 2 xx 3 = 12, 6+3 xx 3 = 15 etc. If it is known that there are six rooms on each floor, how many numbers on the fifteenth floor are prime numbers ?
