For 10 points, name this French mathematician famous for his little and last theorems.
One theorem named for this man, generalized by Euler's totient theorem, states that for an integer a and a prime number p, a to the p power is congruent to a modulo p. Andrew Wiles proved another theorem named for this man, which states that there are no integers a, b, and c such that a to the x plus b to the x equals c to the x when x is an integer greater than two.
