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.
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
Well, friend, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number, not a composite number, because it can only be divided by 1 and itself. Remember, every number is unique and special in its own way, just like you are unique and special too.
43 is a prime number, and 43 and 66 do not share any common factors beyond 1. Therefore, the only GCF is, informally, one.
No, it is not.
43 is a 2 digit odd number but it is a prime number
The GCF of any two consecutive numbers is 1.
