Finding the GCF (Greatest Common Factor) of a data set

Given Data Set 16 and 24

Method 1: List the Factors for each number in the data set

16: 1, 2, 4, 8, 16 List the factors
24: 1, 2, 3, 4, 6, 8, 12, 24 Circle (highlight) the GCF

GCF = 8

Method 2: Use Prime Factorization

1. Create a Prime factorization tree for all numbers given
2. Circle common factors
3. Find the product of the common factors

Method 3: Factor Ladder (upside down cake method)

1. Begin with a factor that all numbers have in common
2. Keep dividing until the numbers have no more common factors
3. Find the product of the numbers divided by.
