The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The greatest common factor of 28 and 90 is 2
The greatest common factor between 9 and 28 is 1. 28 cannot be divided by 9, 6, or 3 to equal a whole number and 9 cannot be divided by 4 or 2.
The GCF of consecutive integers is 1, and so the GCF of 28 and 29 is 1.

Why is 7 the greatest common factor of 28 and 63?
7 is a factor of 28 because 4 x 7 equals 28. 7 is a factor of 63 because 9 x 7 = 63. That makes 7 a common factor of 28 and 63. The factors of 28 that are larger than 7 are 14 and 28. The factors of 63 that are larger than 7 are 9, 21 and 63. Since none of those numbers are the same, that makes 7 the greatest common factor of 28 and 63.
