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.
Yes, 43 is a two-digit odd number because it has two digits and is not divisible by 2. It is a prime number because it can only be divided by 1 and itself. A composite number is a positive integer greater than 1 that has at least one positive divisor other than 1 and itself, so 43 is not a composite number.
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.
The GCF of any two consecutive numbers is 1.
