The greatest common factor of 77 and 84 is 7.
The greatest common factor of 42, 77 and 84 is 7.
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.
The factors of 77 are:1, 7, 11, 77The factors of 84 are:1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are:1, 7The Greatest Common Factor (GCF) is:7
It is: 7
1 and 7.
GCF(84, 77, 49) = 7.
1 and 7
The Greatest Common Factor (GCF) is: 7
28
Since 21 is a factor of 84, it is automatically the GCF and all of its factors are common.
Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42Factors of 77: 1, 7, 11, 77Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84GCF (42, 77, 84) = 7
The Highest Common Factor (HCF) of 21, 77, and 84 is 7. To find the HCF, you need to identify the common factors of the numbers and determine the highest one they all share. In this case, the factors of 21 are 1, 3, 7, 21; the factors of 77 are 1, 7, 11, 77; and the factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84. The highest common factor among them is 7.
