4. 12x^2-64x-256=4(3x^2-16x-64)
The greatest common factor is the highest number that divides exactly into two or more numbers. 256: 1, 2, 4, 8, 16, 32, 64, 128, 256 625: 1, 5, 25, 125, 625, The GCF for 256 and 625 is 1.
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 160 are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, and 160. The factors of 256 are 1, 2, 4, 8, 16, 32, 64, 128, and 256. The common factors are 1, 2, 4, 8, 16, and 32. Therefore, the greatest common factor is 32.
The greatest common factor is 2
