(2+1)(2^2+1)(2^4+1)(2^8+1).(2^32+1)
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1).(2^32+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1).(2^32+1)
=(2^4-1)(2^4+1)(2^8+1).(2^32+1)+1
=(2^8-1)(2^8+1).(2^32+1)+1
=(2^16-1).(2^32+1)+1
.
=(2^32-1)(2^32+1)+1
=2^64-1+1
=2^64
=(2-1)(2+1)(2^2+1)(2^4+1)(2^8+1).(2^32+1)
=(2^2-1)(2^2+1)(2^4+1)(2^8+1).(2^32+1)
=(2^4-1)(2^4+1)(2^8+1).(2^32+1)+1
=(2^8-1)(2^8+1).(2^32+1)+1
=(2^16-1).(2^32+1)+1
.
=(2^32-1)(2^32+1)+1
=2^64-1+1
=2^64
