Example: 30/42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Find the greatest common factor between the numerator and the denominator, then divide the numerator by greatest common factor and then divide denominator by greatest common factor, for a new simplified fraction.
find the greatest common factor divide by it then you have an answer
you find the GCF (GREATEST COMMON FACTOR) then you divide or multiply you can pick and then you get you simplest from of the fraction
you take a fraction say, 6/12 and you find the GCF (Greatest common factor) of both of the numbers. in this case It would be 6 because 6 is the GCF (Greatest common factor)
The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. If you find the GCF of the numerator and denominator of a fraction and divide them by it, you will find the simplest form of the fraction. If the GCF is 1, the fraction is already in its simplest form.
If the GCF of the numerator and the denominator is 1, the fraction is in its simplest form.
1) You use the Euclidian algorithm to find the greatest common factor between the numerator and the denominator. 2) You divide numerator and denominator by this greatest common factor. This will give you an equivalent fraction in simplest terms.
To simplify a fraction, the numerator and denominator are divided by a common factor. The simplification process is continued until there is no common factor. By dividing the numerator and denominator by their greatest common factor no further simplification is possible.
-- Find the greatest common factor of the numerator and denominator . . . it is 4 .-- Divide the numerator and denominator both by their greatest common factor (which is 4).-- The fraction 32/4 becomes 8/1 or simply 8 .Note:This method works for any fraction that needs to be simplified,but the greatest common factor will not always be 4 .
All you have to do is find the Greatest Common Factor (GCF) of the numerator and the denominator then divide the fraction by the GCF to simplify a fraction. Hope this helps
Find the GCF of the numerator and denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
