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.
