To find the greatest common factor (GCF) of 28, 42, and 63, we first need to find the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The GCF of 28, 42, and 63 is the largest number that appears in the factor lists of all three numbers, which is 7.

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 32, 42, and 63 is 1
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
The greatest common factor is 21
The GCF is 7.
