E134  Theoremata circa divisores numerorum
(Theorems on divisors of numbers)
Summary:
This paper contains Euler'is second proof of the EulerFermat theorem, which Euler presents as a consequence
of the theorem that (a+b)^{p} = a^{p}+b^{p}
(mod p). This paper also includes results about possible divisors of a^{2n}
+ b^{2n}, and Euler uses this to show again that F_{5} is not prime.
According
to C. G. J. Jacobi, a treatise with this title was read to the Berlin Academy on March 23, 1747.
According to the records, it was presented to the St. Petersburg Academy on September 2, 1748.
