If youn have 64 and 128, your gcf is 64 and lcm is 128

64 is.

x3 + 4x2 - 16x - 64 = (x + 4)(x + 4)(x - 4).

a=64 b=8 (x+16x+64)=(x+8)^2

x3 + 4x2 + 16x + 64 =x2*(x + 4) + 16(x + 4) = (x + 4)*(x2 + 16) which has no further real factors.

to factor (x2-16x+64), you need to find two number whose product is 64 and whose sum is 16. These two numbers are 8 and 8. (x2-16x+64)=(x-8)(x-8)

Too bad that's not x^2 - 16x + 64 which factors to (x - 8)(x - 8)
