4294967297

4,294,967,297 is the fifth Fermat number, equal to \(2^{2^5} + 1\). It was proven to be composite by Euler in 1732, disproving Fermat's conjecture that all numbers of the form \(2^{2^n} + 1\) are prime. It can be factored into 641*6700417.https://www.wolframalpha.com/input/?i=4294967297
