gf(2) Square-free factorization (sff)
Find and remove all squared factors from f.
f = b0110011001110111111000100000000101000110010100001000111110110111
f = 0x6677e20146508fb7
f = x62 + x61 + x58 + x57 + x54 + x53 + x52 + x50 + x49 + x48 + x47 + x46 + x45 + x41 + x32 + x30 + x26 + x25 + x22 + x20 + x15 + x11 + x10 + x9 + x8 + x7 + x5 + x4 + x2 + x + 1
Find the derivative of f (f')
f' = b0001000100010001010100010000000000000001000000000100010101010001
f' = 0x1111510001004551
f' = x60 + x56 + x52 + x48 + x46 + x44 + x40 + x24 + x14 + x10 + x8 + x6 + x4 + 1
Since f' does not equal zero, find g=gcd(f,f')
g = b0000000000000000000000000000000000000000000000000000000000000001
g = 0x0000000000000001
g = 1
Since g equals one, f has no square factors.
Result (f factored into square-free factors)
f = (b0110011001110111111000100000000101000110010100001000111110110111)
f = (0x6677e20146508fb7)
f = (x62 + x61 + x58 + x57 + x54 + x53 + x52 + x50 + x49 + x48 + x47 + x46 + x45 + x41 + x32 + x30 + x26 + x25 + x22 + x20 + x15 + x11 + x10 + x9 + x8 + x7 + x5 + x4 + x2 + x + 1)
