Factoring

GREATEST COMMON FACTOR
•
To factor a number means to write the number as the product of
two or more numbers
•
For example we will factor the number 12:
12= 6x2

FINDING THE GCF
To find the GCF you will need a set of numbers and then will have to
factor those numbers
For example
we will find the GCF of 30,20, and 15
30= 2x3x5
20= 2x2x5
15= 3x5
The highest number that all those factored number have in common is 5
