Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.

Do you do factors of the greatest common factor or multiples?
When doing fractions it is the greatest common factor (GCF) and the least common multiple (LCM). You want the GCF when you are reducing fractions to their simplest form. When changing the denominators to a common one, you want the LCM.
What is the relationship between least common multiple and greatest common faction?
Least common multiple is needed to find the least common denominator when adding or subtracting fractions with different denominators Greatest common factor is needed when reducing fractions to their lowest terms
Where is greatest common factor use?
The greatest common factor is used to reduce fractions.
What do you use greatest common factor for?
To reduce fractions
Greatest common factor life application?
One common application of greatest common factors is to simplify fractions. Note that you don't necessarily need the GREATEST common factor; you can simplify by dividing both numbers by any common factor, and then continue looking for additional factors.

What are the factors and greatest common factor for?
Finding the greatest common factor helps when you are reducing fractions.
How can knowing the greatest common factor and least common multiple help you when you add subtract and multiply fractions?
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
