The common factors of 22 and 42 are: 1 and 2
The common factors of 42 and 77 are: 1 and 7
The GCF of 42 and 86 is 2. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
The common factors of 21 and 42 are the numbers that divide both 21 and 42 without leaving a remainder. The factors of 21 are 1, 3, 7, and 21, while the factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors of 21 and 42 are 1, 3, 7, and 21.
There is neither a greatest common factor nor common factors of a single number, such as 42, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Examples: The common factors of 25 and 42 are only 1; the greatest common factor is 1. The common factors of 36 and 42 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 49 are 1 and 7; the greatest common factor is 7. The common factors of 42 and 60 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 42 and 70 are 1, 2, 7, and 14; the greatest common factor is 14.
The common factors of 42 and 273 are 1, 3, 7 and 21.
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 273 are: 1, 3, 7, 13, 21, 39, 91, 273
The GCF of 42 and 273 is 21. 42 = 2 x 21 273 = 13 x 21
The common factors are: 1, 2
1, 2, 7 and 14 are the common factors of 28 and 42. Since all of the numbers are common factors, we will not be able to select two.
The prime factors of 28 are 2,2 and 7 The prime factors of 42 are 2,3 and 7 Thus the common factors are 1,2,7 and 14.
The factors of 14 are 1, 2, 7, and 14 The factors of 42 are 1, 2, 3, 7, 14, 21, and 42 The Common factors of 14 and 42 are 1, 2, 7, and 14
The common factors are: 1, 2
The common factors are: 1, 2, 7, 14.
Factors of 28... 1,2,4,7,14,28 Factors of 42... 1,2,3,6,7,14,21,42 GCF = 14
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42 For them to be common, they need to be compared to another set of factors.
1, 3, 7, and 21 are all common factors of 21 and 42.
