Divide 4, the GCF, into both numbers. 8/12 can be reduced to 2/3.
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.
In math, GCF stands for greatest common factor.
Greatest common factor of 39,63 and 144 is 3. 3 is the highest factor that can divide 39,63 and 144 without a remainder.
That's a misrepresentation of the term "greatest common factor," or GCF, which is the largest number that will divide evenly with no remainder into all the members of a set of two or more given numbers.
The greatest common factor of the numbers 466 and 724 is the number 2. The greatest common factor is the largest number that will divide evenly into at least two different numbers.
You have to find the greatest common factor between the numerator and the denominator. Then you divide numerator and denominator by this greatest common factor. There are several methods to find the greatest common factor. Note that "dividing only once" is not necessarily to your advantage; it is easier to divide by ANY common factor you find, and then continue looking for additional factors.
One place where this is used is to simplify fractions: you need to find the greatest common factor, then divide top and bottom by this greatest common factor.Also, in factoring expressions - you can take out the greatest common factor. For example (using "^" for power): 5x^2 + 10x has the greatest common factor 5x; so this can be taken out as a common factor, resulting in 5x(x + 2).
in what kind of problem?
The greatest common factor (or GCF) is the highest number that can divide into aanother number, and not have a decimal (whole number).
The greatest common factor, or GCF, is the largest integer that will divide evenly with no remainder into all the members of a given set of numbers.
The greatest common factor of 8 and 28 is 4, because 4 is the highest number that will divide into both evenly.
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
