Prime and Composite Numbers

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

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

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

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

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

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