3. Greatest common factor

4. Factors of a number
The factors of a whole number are the whole numbers that divide evenly into that number. The factors of 4 are: The factors of 12 are: The factors of 5 are:

5. Greatest common factor
The Greatest Common Factor or GCF for a group of whole numbers is the greatest whole number that will divide evenly into every number in the group of numbers. Examples: Find the GCF for each group of numbers and and and 7

6. Greatest common factor
4. 6, 12, , 10, , 10, and and and , 9, , 8, , 12, 28

7. Greatest common factor - variables
If a list of variable terms has a common variable then the GCF is the common variable to the lowest power that the common variable has in the group of terms. Examples: Find the GCF for each group of terms. 1. x2 and x6 2. y3 and y4 3. x4 and y4

8. Greatest common factor - variables
4. x4, x2, x5 5. y3, y4, y 6. x3y3, xy2, y5 7. x2, x3, x4 8. y, y2, y3 9. x4, x3y, xy

9. GCF of a polynomial
To find the GCF for a polynomial, find the GCF for all of the coefficients and then find the GCF for the variables in each term. Examples: Find the GCF for each polynomial
