Abstract | As the name of the paper implies, a converse of Fermat's Little Theorem (FLT) is stated and proved. FLT states the following: if p is any prime, and x any integer, then x[superscript p] [equivalent to] x (mod p). There is already a well-known converse of FLT, known as Lehmer's Theorem, which is as follows: if x is an integer coprime with m, such that x[superscript m-1] [equivalent to] 1 (mod m), and if there exists no integer e less than m-1 such that x[superscript e] [equivalent to] 1 (mod m), then m is prime. The new converse in question states the following: if p is any prime and x[superscript p] [equivalent to] x (mod p), where x is known only to be algebraic, then x must be an integer (mod p).
