The GCF is 21.
To find the greatest common factor (GCF) of 63, 84, and 126, we first need to list the factors of each number. The factors of 63 are 1, 3, 7, 9, 21, and 63. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126. The GCF is the largest number that appears in all three lists, which in this case is 21.
63 and 84's highest common factor is 21.
The least common multiple of the numbers 14, 49, 63 and 84 is 1,764.
The GCF is 7.
The GCF is 21.
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!
