Prime Factorization
Background: We can break down ANY number as a product of prime numbers.
Remember a prime number is a number that is only divisible by itself and 1. We
can use a factor tree to show the breakdown of any number.
Example 1 : Use a factor tree to find the prime factorization of 54
**The order doesn’t matter! We will write the
final answer using the numbers on the bottom
row in order from smallest to biggest.
Answer: 54 = 2 ∙ 3 ∙ 3 ∙ 3
You try! - Use a factor tree to find the prime factorization of each number.
