The GCF is 2.
The Least Common Multiple (LCM) for 42 86 is 1,806.
The gcf of 43 and 129 is 43, so the two digit number must be 43; howeverthe gcf of 86 and 129 is also 43, so the two digit number must be 86; howeverthe gcf of 22 and 86 is only 2 and the gcf of 22 and 43 is only 1, no neither 43 nor 86 has a gcf of 43!Hint:You cannot have a COMMON factor with only onenumber - common implies at least two numbers.The greatest COMMON factor is the largest number that divides all the numbers and depends upon all the numbers - it makes no sense to ask for the greatest COMMON factor of a single number.
The GCF is 1.
2 x 43 = 862 x 7 x 11 = 154The GCF is 2.
The greatest common factor of 24 , 86 = 2
The greatest common factor of 16 and 86 is 2.
The Greatest Common Factor (GCF) is: 2
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 greatest factor is 86 which is a factor of 86, though not of 44. The greatest COMMON factor, though not requested, 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.
