====== Beal's conjecture ====== >If Ax + By = Cz, where A, B, C, x, y and z are positive integers and x, y and z are all greater than 2, then A, B and C must have a common prime factor. > >Source : [[https://www.bealconjecture.com/|bealconjecture.com]] The conjecture was proposed in 1993 by self-taught mathematician [[https://en.wikipedia.org/wiki/Andrew_Beal|Andrew Beal]], who was working on aspects of Fermat's Last Theorem. The //American Mathematical Society// is holding in trust a $1,000,000 [[http://www.ams.org/prizes-awards/paview.cgi?parent_id=41|prize fund]] for anyone who can prove (or disprove) the conjecture.
