Euler generalized Fermat’s Theorem in the following way: if gcd (x,n) = 1 then xφ(n) ≡ 1(modn), where φ is the Euler phi-function. It is clear that Euler’s result cannot be extended to all integers x in the same way Fermat’s Theorem can; that is, the congruence xφ(n)+1 ≡ x(modn)is not always valid.
