2^32-1
= (2^16+1)(2^16-1)
= (2^16+1)(2^8+1)(2^8-1)
= (2^16+1)(2^8+1)(2^4+1)(2^2+1)(2+1)(2-1)
= (2^16+1)(2^8+1)(2^4+1)(2^2+1)(2+1)
代入原式：
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)/(2^32-1)
＝ (2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)/［(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)］
＝ 1
= (2^16+1)(2^16-1)
= (2^16+1)(2^8+1)(2^8-1)
= (2^16+1)(2^8+1)(2^4+1)(2^2+1)(2+1)(2-1)
= (2^16+1)(2^8+1)(2^4+1)(2^2+1)(2+1)
代入原式：
(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)/(2^32-1)
＝ (2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)/［(2+1)(2^2+1)(2^4+1)(2^8+1)(2^16+1)］
＝ 1
