Divisibility is a subject in mathematics that, when presented to students of elementary school or even also of high school, can be considered difficult for a large number of them. The difficulties often occur for lack of prerequisites knowledge and even by creating a kind of barrier on the subject. This work aims to present a general and simplified rule to establish divisibility criteria for natural primes greater or equal to 7. Divisibility criteria are rules for determining divisibility of numbers without the need to perform long division processes. In particular, we study the criterion of divisibility by 7, the largest prime number of one digit and very little explored in teaching materials of the Official Network of São Paulo State Education
