The Greatest Common Factor (GCF) of x^6 and x^4 is x^4. When finding the GCF of algebraic terms, you look for the highest power of the variable that appears in both terms. In this case, x^4 is the highest power of x that is common to both x^6 and x^4. Therefore, the GCF is x^4.

GCF of variables with exponents The GCF is the common variable with smallest exponent. example 9x4 - 27x6 the gcf is 9X4 because: 9x4 (1-3x2) = 9x4 - 27x6 In the same way: X5 is the GCF of X10 + x5 -x6 Because X5 ( X5 + 1 -x1) = X10 + x5 -x6 Remember the exponent rule if you are multiplyin the same base, you keep the base and add the exponents Hope this helps Btw this does not help me! anna
72 ---> 2 x 36 2x36 ---> 2 x 6 x6 2 x 6 x6 ---> 2 x 3 x 3x 3 -x3 good luck

x6 - y6 = (x3)2 - (y3)2 = (x3 + y3) (x3 - y3) = (x + y)(x2 - xy + y2)(x - y)(x2 + xy + y2)
