Factors, Primes & Composite Numbers 6 th grade math

Definition  Product – An answer to a multiplication problem. 7 x 8 = 56 Product

Definition  Factor – a number that is multiplied by another number to give a product. 7 x 8 = 56 Factors

Definition  Factor – a number that divides evenly into another. 56 ÷ 8 = 7 Factor

What are the factors?

Definition  Prime Number – a number that has only two factors, itself and is prime because the only numbers that will divide into it evenly are 1 and 7.

Examples of Prime Numbers 2, 3, 5, 7, 11, 13, 17, 19 Special Note: One is not a prime number.

Definition  Composite number – a that has more than two factors. 8 The factors of 8 are 1, 2, 4, 8

Examples of Composite Numbers 4, 6, 8, 9, 10, 12, 14, 15 Special Note: Every whole number from 2 on is either composite or prime.

Our Lonely 1 Special Note: One is not a prime nor a composite number. It is not prime because it does not have exactly two different factors. It is not composite because it does not have more than 2 factors.

Definition  Prime Factorization – A way to write a composite number as the product of prime factors. 2 x 2 x 3 = 12 or 2 x 3 = 12 2

How to Do Prime Factorization Using a Factor Tree 48 Step 1 – Start with a composite number. Step 2 – Write down a multiplication problem that equals this number or any pair of factors of this number. 6 x 8 = 48

How to Do Prime Factorization Using a Factor Tree Step 3 – Find factors of these factors. 6 x 8 = 48 2 x 3 x 2 x 4 = 48

How to Do Prime Factorization Using a Factor Tree Step 4 – Find factors of these numbers until all factors are prime numbers. 6 x 8 = 48 2 x 3 x 2 x 4 = 48 2 x 3 x 2 x 2 x 2 = 48

How to Do Prime Factorization Using a Factor Tree Step 5 – Write the numbers from least to greatest. 6 x 8 = 48 2 x 3 x 2 x 2 x 2 = 48 2 x 2 x 2 x 2 x 3 = 48

How to Do Prime Factorization Using a Factor Tree Step 6 – Count how many numbers are the same and write exponents for them. 6 x 8 = 48 2 x 3 x 2 x 2 x 2 = 48 2 x 2 x 2 x 2 x 3 = 48 2 x 3 = 48 4

Prime factor this number 4 2 x 2 2 = 4 2 = 4

Prime factor this number 6 2 x 3= 6

Prime factor this number 9 3 x 3= 9 3 = 9 2

Prime factor this number 10 2 x 5= 10

Prime factor this number 12 3 x 4 2 x 3 = 12 2 = 12 3 x 2 x 2 = 12 2 x 2 x 3 = 12

Prime factor this number 22 2 x 11= 22

Prime factor this number 14 2 x 7= 14

Prime factor this number 15 3 x 5= 15

Prime factor this number 16 4 x 4 2 = 16 4 = 16 2 x 2 x 2 x 2 = 16

Prime factor this number 18 3 x 6 2 x 3 = 18 2 = 18 3 x 2 x 3 = 18 2 x 3 x 3 = 18

Prime factor this number 20 4 x 5 2 x 5 = 20 2 = 20 2 x 2 x 5 = 20
