No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
Keep dividing the numerator and denominator by any common factor they have, until they have no common factor except ' 1 '.
By looking for common factors - factors that appear in both numbers - and dividing both numbers by the same factor.
You can't simplify that. There are no common factors.You can't simplify that. There are no common factors.You can't simplify that. There are no common factors.You can't simplify that. There are no common factors.
You don't need a common denominator to divide fractions.
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.
They are useful in reducing fractions and to simplify radicals. They are useful in reducing fractions and to simplify radicals.

Finding the GCF will help you when you are trying to reduce fractions.
Cancelling out common factors means you are working with smaller numbers. It is usually, but not always, beneficial.
To simplify fractions.
