Best Answer

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.

Since 161 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 161 is 161
