More specifically, it was shown by van der Poorten and Schlickewei [14] and, independently, by Evertse [4, Corollary 3], using Schlickewei's p-adic analogue of Schmidt's Subspace Theorem [7], that the greatest prime factor of un tends to ∞ as n→∞. In a similar note, effective ...
The exponent of prime number 809 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 809 has exactly 2 factors. Factors of 809: 1, 809 Factor pairs: 809 = 1 x 809 809 has no square factors that allow its square root to be simplified. √809 ≈ 28.4429253066558. ...
