The factors of 84 are:
1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
The factors of 126 are:
1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
The common factors are:
1, 2, 3, 6, 7, 14, 21, 42
The Greatest Common Factor:
GCF = 42
The GCF of 84, 126 and 294 is 42.
The GCF is 6.
The greatest common factor of the numbers 30, 84 and 126 is 6.
The factors of 84 are 1,2,3,4,6,7,12,14,21,28,42 and 84. To find a greatest common factor, you need to compare them to another number's factors.
Answer=7 because 7x9=63 7x12=84 7x18=126
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 GCF is 42.
42
The GCF is 21.
28
Since 21 is a factor of 84, it is automatically the GCF and all of its factors are common.
The GCF of 84 and 126 is 42.
