Learning Objective
I can use find the greatest common factor of two numbers and use the GCF to solve word problems.
- 1
The greatest common factor (GCF) is the largest positive integer that divides two or more given integers without leaving a remainder.
- 2
To find the GCF using prime factorization, you express each number as a product of its prime factors and then multiply the lowest power of each common prime factor.
- 3
The GCF is invaluable in word problems when you need to divide distinct quantities into the largest possible equal parts, like making identical groups from different items.
