Solution:
First, we factor
27x6+1=(3x2)3+1=(3x2+1)(9x4−3x2+1)=(3x2+1)((9x4+6x2+1)−9x2)=(3x2+1)((3x2+1)2−(3x)2)=(3x2+1)(3x2+3x+1)(3x2−3x+1)
Letting x=10, we get that 27,000,001=301⋅331⋅271. A quick check shows that 301=7⋅43, so that 27,000,001=7⋅43⋅271⋅331. Each factor here is prime, and their sum is 652.
