(2+1)×(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= (2-1)(2+1)×(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= (2²-1)(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= ...
= (2的64次方-1)+1
= 2的64次方
(2+1)×(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= (2-1)(2+1)×(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= (2²-1)(2²+1)×(2的4次方+1)···(2的32次方+1)+1
= ...
= (2的64次方-1)+1
= 2的64次方
