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.

There is one "greatest common factor", not several.

The greatest common factor of 86 and 42 is the same as the greatest common factor of 42 and 2 - where 2 is calculated as the remainder of the division of 86 by 42.

GCF of 96 and 86 is 2

Answer: 2 One way to approach this is to look at the difference between 84 and 86, which is 2. The greatest common factor of two numbers cannot be larger than the difference between the two numbers and must be a factor of the difference. Since both 84 and 86 are divisible by 2, the greatest common factor is 2.

43 X 2 equals 86. 43 is a prime number. 43 is the GCF of 43 and 86.

The Greatest Common Factor (GCF) is: 2

The greatest factor is 86 which is a factor of 86, though not of 44. The greatest COMMON factor, though not requested, is 2.

GCF =2 76-1,2,4,19,38,76 86-1,2,43,86

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 86, 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 86 are 1, 2, 43, and 86. Examples: The common factors of 8 and 86 are 1 and 2; the greatest common factor is 2. The common factors of 86 and 387 are 1 and 43; the greatest common factor is 43.

The greatest common factor of two numbers is their HCF.The HCF of 53 and 86 is 1 as 53 is a prime number and does not have any factors other than 1 and itself so, the greatest common factor of 53 and 86 is 1.

It is: 2
