Prime and Composite Numbers
Prime Numbers- have only 2 factors: 1 and the number itselfComposite 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 remaindersMultiples 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
Write this in your INTERACTIVE Notebook's table of contents!
