3
The GCF is 3.
168x3 - 45x2 + 3x = 3x(56x2 - 15x + 1) = 3x(7x - 1)(8x - 1)
You can take 3 out of both of those.
If x>1 then the gcf is 15x. If x<1 then the gcf is 15.
The GCF is 15x^2y^2
The GCF is 3x.
The GCF is 3x.
The GCF of 30 x^2 and 45x is 15x. The GCF of 30 and 45 is 15, and the GCF of x squared and x is x.
The GCF is 15x.
The GCF is 5x
The GCF is 5x2
The GCF of 45 and 3 is 3. The GCF of 45 and 2 is 1.
