Thanks to the accessible presentation of the material, the reader can gain an understanding of the properties of integers related to their factorization into prime factors. Almost all of the material is designed for those who have knowledge only of the school mathematics curriculum, although there are also more complex explanations that assume knowledge of higher mathematics. At the end of the book, there is an article by the distinguished mathematicians V. M. Tikhomirov and V. V. Uspensky dedicated to the life and scientific path of L. G. Schnirelmann. The book is intended for high school students, junior university students, and all those interested in mathematics.
