Applications of Fermat’s and Euler’s Theorems

  • Lindsay N. Childs
Part of the Undergraduate Texts in Mathematics book series (UTM)


This chapter is devoted to some applications of Fermat’s and Euler’s theorems, mostly to numbers: decimal expansions, testing numbers for primeness, factoring numbers. Perhaps the most striking application, in Section B, is to the design of a cryptographic system, the RSA cryptosystem, which has spawned an enormous amount of research on factoring large numbers since the system was discovered in the late 1970s.
