[tex](2 + 1)( {2}^{2} + 1)( {2}^{4} + 1)( {2}^{8} + 1)( {2}^{16} + 1) - {2}^{32} [/tex]

[tex] = 3(4 + 1)(16 + 1)(64 + 1)[ {(2}^{8} )^{2} + 1] - ( {2}^{8} )^{4} [/tex]

[tex] = 3 \times 5 \times 17 \times 65( {64}^{2} + 1) - {64}^{4} [/tex]

[tex] = 16575(4096 + 1) - 16777216[/tex]

[tex] = 16575 \times 4097 - 16777216[/tex]

[tex] = 67907775 - 16777216[/tex]

[tex] = 51130559[/tex]
