1. Prime and Composite Numbers

2. Prime Numbers- have only 2 factors: 1 and the number itself
Composite Numbers- have at least three factors

3. 0 and 1 are neither prime nor composite.
The only even prime number is 2.
2 and 3 are the only consecutive prime numbers

4. Relatively Prime Numbers- their greatest common factor is 1.
This means that the only number that divides into both numbers is 1.

5. Prime factorization- way to express a composite number as a product of prime numbers.

6. Factors divide a number exactly with no remainders
Multiples are the product that results from multiplying by the integers 1, 2, 3, 4,…

7. Factor tree- helps you determine the prime factorization of composite numbers
