The GCF is 7.
3276
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. To find the GCF of 28 and 63, we need to list the factors of each number. The factors of 28 are 1, 2, 4, 7, 14, and 28, while the factors of 63 are 1, 3, 7, 9, 21, and 63. The largest number that appears in both lists is 7, so the GCF of 28 and 63 is 7.
The GCF is 7.
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 GCF is 7.
91 - 63 = 28
The GCF of 28, 84, and 91 is 7.
