When you need to reduce fractions.
The greatest common factor is used to reduce fractions.
It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
divisor
To reduce fractions
Get the greatest common factor first. For example, you might use Euclid's Algorithm - the first step is that the greatest common factor of 5030 and 100 is the same as the greatest common factor of 100 and 30 (where 30 is the remainder of the division of 5030 / 100). Once you get the greatest common factor, the common factors of the two numbers are simply all the factors of this greatest common factor.

The greatest common factor of 6 and 9 is 3.

Just use the GCF(greatest common factor
divisor
It doesn't matter what you use, you still need at least two numbers to find a GCF. If that's 3 and 6, the GCF is 3.
The greatest common factor is a function of two numbers-- it is the greatest factor that the numbers have in common. The concept does not apply to a single number. Now you can use the same number twice and ask what is the greatest common factor of 240 and 240 and the answer would be 240.

When simplifying fractions.
Yes, they do.
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
It won't help. The lowest common factor of any two positive integers is 1.
