The common factors of 63 and 84 are: 1, 3, 7, and 21
Factors of 63: 1, 3, 7, 9, 21, 63.Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.GCF (63, 84, 126) = 21
The factors of 20 are: 1, 2, 4, 5, 10, 20 The factors of 63 are: 1, 3, 7, 9, 21, 63
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.
