every composite number expressed as a product of a prime number.

Concept Summary

Concept Summary

Prime

A whole number that has exactly two factors, 1 and the number itself.

11, 13, 25

Composite

A number greater than 1 with more than two factors.

6, 10, 18

Neither prime nor composite

1 has only one factor. O has an infinite number or factors.

0, 1

Slide 3

Identify Prime and composite, or neither

Identify Prime and composite, or neither

28: The factors of 28 are 1 and 28, 2 and 14, and 4 and 7. Since 28 has more than two factors, it is a composite number.

11: The factors of 11 are 1 and 11. Since there are exactly two factors, 1 and the number itself, 11 is a prime number.

Slide 4

Remember

Remember

Factor: when two or more numbers are multiplied, each number is called a factor of the product.

Prime Number: a whole number that has exactly two unique factors, 1 and the number itself.

Composite number: a number greater than 1 with more than two factors.

Slide 5

Prime Numbers and Prime Factorization

Prime Numbers and Prime Factorization

Every Composite number can be written as a product of prime numbers

6 = 2 x 3

8 = 2 x 2 x 2

12= 2 x 2 x 3

Slide 6

Prime Factors

Prime Factors

Factors that are prime numbers are called prime factors. You can use Factor Tree to find prime factors. This one shows the prime factors of 50

50
