Best Answer

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.

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.
