乘以x-1,再除以x-1
=(x-1)(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^2-1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^4-1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^8-1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^16-1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^32-1)(x^32+1)(x^64+1)/(x-1)
=(x^64-1)(x^64+1)/(x-1)
=(x^128-1)/(x-1)
=(x-1)(x+1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^2-1)(x^2+1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^4-1)(x^4+1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^8-1)(x^8+1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^16-1)(x^16+1)(x^32+1)(x^64+1)/(x-1)
=(x^32-1)(x^32+1)(x^64+1)/(x-1)
=(x^64-1)(x^64+1)/(x-1)
=(x^128-1)/(x-1)
