The gcf of 43 and 129 is 43, so the two digit number must be 43; however
the gcf of 86 and 129 is also 43, so the two digit number must be 86; however
the 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.
It's like a number with two numbers. like: 12 43 99 35
No, it is not.
Yes, it is.
The GCF is 1.

42 is composite, 43 is prime.
No, it is not.
No, it is not.
The GCF is one because 43 is a prime number.
43 is a prime number, 76 does not divide by 43 so GCF is 1
It's like a number with two numbers. like: 12 43 99 35
43 is a 2-digit odd number. It is prime.
No, it is not.
43 is a prime number, and 43 and 66 do not share any common factors beyond 1. Therefore, the only GCF is, informally, one.
43 is a 2 digit odd number but it is a prime number
The GCF of any two consecutive numbers is 1.
