How do you find the GCF in Algebra 1?
To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together. Bam! The GCF!
What is GCF in math algebra?
The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
How do you find the GCF of numbers and variables?
You can also determine the GCF if you have both numbers and variables. Factorize the numbers and identify all common factors. To get the GCF multiply all common factors. You can use the greatest common factor to simplify fractions.
