Transcript and Presenter's Notes

Finding The Greatest Common Factor

- Ms. Lusters 5-04

Greatest Common Factor

- The greatest common factor is the largest common

factor of two numbers. Factors are all of the

numbers that divide into a given number equally. - The greatest common factor can be found by

comparing all the factors of two numbers or by

finding the prime factorization of two numbers

Finding Factors

- Finding the factors of a number can be done by

sequentially dividing numbers into the product.

When the factors begin to repeat you have found

all factors.

Finding Factors

- Find the factors of 18
- 1 goes into 18, 18 times.
- 2 goes into 18, 9 times.
- 3 goes into 18, 6times.
- 4 does not divide 18 evenly.
- 5 does not divide 18 evenly.
- We are now back to 6. We have found all factors

of 18. - 1, 2, 3, 6 and 18

Finding The GCF Using Factors

- Determine the greatest common factor of two

numbers by finding all the factors for the two

numbers then comparing them. The largest common

factor of the two numbers is their greatest

common factor.

Using Factors

- Find the GCF of 36 and 24
- Factors of 36 1, 2, 3, 4, 6, 9, 12, 18 and 36
- Factors of 24 1, 2, 3, 4, 6, 8, 12 and 24
- The greatest common factor is of 36 and 24 is 12

Using Factors Again

- Find the GCF of 15 and 100
- Factors of 15 1, 3, 5 and 15
- Factors of 100 1, 2, 4, 5, 10, 20, 25,
- 50 and 100
- The greatest common factor of 15 and 100 is 5

Finding the Prime Factorization

- A prime factorization is when a product is broken

down until only prime numbers remain. Prime

numbers are numbers whos only factors and 1 and

them self. A factor tree is useful in finding a

prime factorization.

Prime Factorization

- Break 18 down to only prime numbers.
- 18
- /\
- 9
- /\
- 3 3
- 18 2 2 3

Finding the GCF Using Prime Factorization

- To determine the greatest common factor find the

prime factorization for each number. Find all of

the common prime factors of the two numbers and

multiply them together. Your sum is the GCF.

Using Prime Factorization

- Find the GCF of 36 and 24
- 36 24
- /\ /\
- 2 18 2 12
- /\ /\
- 2 9 2 6
- /\ /\
- 3 3 2 3
- 36 2233 24 2223
- The GCF of 36 and 24 is 22312

Using Prime Factorization Again

- Find the GCF of 21 and 42
- 21 42
- /\ /\
- 3 7 2 21
- /\
- 3

7 - 21 37 42 237
- The GCF of 21 and 42 is 37 21
