The greatest common factor of 40x2 and 20x7 is 20x2
The greatest common factor is the lowest of the powers in this case.
1024 = 2 to the power 10, 2187 = 3 to the power 7. There is no common factor above 1.
The GCF is a.
When a number is raised to a power, the base is raised to an exponent.
The greatest common factor of a variable, raised to different powers, is the LOWEST of the powers - in this case, x to the power 2.
z2 = z * z * 1; z = z * 1. Greatest common factor is z.
The GCF is x2
The GCF is x5
The GCF is a^2b
The GCF is 5r.
the gcf is 4x
