253,747,889/Historical Note

Historical Note on $253 \, 747 \, 889$

The first case of Fermat's Last Theorem, where the value $p$ in the equation $x^p + y^p = z^p$ does not divide one of $x$, $y$ and $z$, had been proved impossible for all values of $p$ up to $253 \, 747 \, 889$, at the point at which Andrew Wiles finally proved it in $1994$.
