The Connection Between Fermat Numbers and Brocard-Ramanujan Type Diophantine Equations

V. Pandichelvi, B. Umamaheswari

Abstract: In this manuscript, the study focuses on the Brocard-Ramanujan type Diophantine equation n!+1=F_t² where F_t=2^k+1, k=2^t, n, t≥0 is a Fermat number, is examined and demonstrates (n,k,t)=(4,2,1) is a sole positive integer solution. Additionally, a Python program to validate this result together with the geometrical presentation is developed.

Keywords: Fermat number, Brocard-Ramanujan Diophantine equation, Integer solution
