The common factors of 63 and 84 are: 1, 3, 7, and 21
The GCF is 21.
1, 3, 7, 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
1, 3, 7 and 21
As 84 = 14 x 6: All the factors of 14 are common to both, ie the common factors of 14 and 84 are: 1, 2, 7, 14; All the multiples of 84 are common to both 14 and 84, ie the common multiples of 14 and 84 are: 84, 168, 252, 336, 420, 504, 588, 672, 756, 840, ...
The GCF of 84 and 63 is 21
The common factors are: 1, 2, 3, 4, 6, 12. 12 is the greatest common factor of 72 and 84. All the factors of 12 will therefore divide by both 72 and 84.
The Greatest Common Factor of 21, 63, 84: 21
least common multiple of 63 and 84 is 252.
63 and 84's highest common factor 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.
