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.
The GCF is 21.
The GCF is 7.
The GCF is 7.
The GCF is 21.
Oh honey, the Greatest Common Factor (GCF) for 42, 63, and 84 is 21. That's the largest number that divides evenly into all three of those numbers. So there you have it, simple as that!
The GCF is 21.
7 is the gcf of 28 35 and 42
The GCF is 7.
The GCF is 7.
