Abstract

The purpose of this paper is finding rules to know whether any number is divisible by some primes (7, 13, 17, 19, 23, 29), so that we use divisibility test and concept of congruence relation in numbers theory. The conclusion of the study arrived that we can know that any natural number is divisible by any prime without doing division.
