It won't help. The lowest common factor of any two positive integers is 1.
Yes, they do.
Prime factorization is a powerful tool when finding the lowest common multiple for use in fractions and greatest common factor when reducing fractions. It is used in algebra to find the possible factoring combinations when factoring polynomials.
You can get hte greatest common factor of three numbers by the same method you use for two numbers: splitting each number into prime factors and taking all common factors. Or, if you want to use Euclid's algorithm: gcf(25, 5, 11) = gcf(gcf(25, 5), 11)). In other words, you can take the greatest common factor of any two numbers, then the greatest common factor of the result and the third number.

When reducing fractions to their simplest form the greatest common factor of their numerator and denominator must be found.
When reducing fractions to their lowest terms.
The greatest common factor is used to reduce fractions.
You don't. The lowest common factor is always 1.
The greatest common factor of 6 and 9 is 3.
Just use the GCF(greatest common factor
divisor
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.
To reduce fractions
When simplifying fractions.
Yes, they do.
As stated, this question does not appear to be particularly useful. The lowest common factor of the numbers is 1. The lowest common MULTIPLE of the three numbers, which could be of use, is 30.
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
