Prime Factorization
How can a number be broken down into smaller parts?
Start thinking
Factor Pairs
• You just worked with factor pairs.• 2 and 15 are factor pairs of 30.
• Example
Factor Pair Example
Prime VS. Composite
Prime Vs. Composite
• Prime Number = has only two factors, one and itself
• Composite Number = has more than two factors
• One = neither prime nor composite.
Use a Factor Tree or Stack Method to complete prime factorization
• Hint: Always start with the lowest prime number 2 when factoring. If 2 doesn’t divide in, then try 3.
• Write the prime factorization of 48.
Write the prime factorization of 45.
