(2^2+1)(2^4+1)(2^8+1)(2^16+1)(2^32+1) It should be simple

Just multiply (2 ^ 2-1) by (2 ^ 2-1) (2 ^ 4 + 1) (2 ^ 8 + 1) (2 ^ 16 + 1) (2 ^ 32 + 1) = (2 ^ 2-1) (2 ^ 2 + 1) (2 ^ 4 + 1) (2 ^ 8 + 1) (2 ^ 16 + 1) (2 ^ 32 + 1) / (2 ^ 2-1) = (2 ^ 4-1) (2 ^ 4 + 1) (2 ^ 8 + 1) (2 ^ 16 + 1) (2 ^ 32 + 1) / (2 ^ 2-1) = (2 ^ 64-1) / (2 ^ 2 -
