All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. Specific sets of numbers will have specific lists of common factors. The largest number on the list of common factors is the greatest common factor, or GCF. It is the largest number that will divide evenly with no remainder into a set of given numbers.
The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.

Actually, both can be true, but the answer your teacher is probably looking for is "greatest."
True. By definition for two numbers to be relatively prime they must not share any common factors. So their greatest (and only) common factor would be 1.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers. The greatest common factor of 36 and 49 is 1
