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 30, 60, 75, and 90 is 15.

To find the greatest common factor (GCF) of 30, 60, 75, and 90, we first need to find the factors of each number. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 75 are 1, 3, 5, 15, 25, and 75. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.
