  1. The Greatest Common Factor (GCF)of 2 numbers is the largest number that can divide into both numbers. Find the GCF of 8and 24. Write the prime factorization of each number.

  2. More practice with prime factorization

  3. Prime Factorization of 8

  4. Prime Factorization of 24

  5. GCF of 8 and 24 • The prime factorization of 8 is: 2 x 2 x 2 = 8 • The prime factorization of 24 is: 2 x 2 x 2 x3 = 24 • The shared factors are 2x2x2 so the GCF is 8

  6. PRIME FACTORIZATION

  7. Find the GCF of 42 and 60 • = 2 • 3 • 7 • 60 = 2 • 2 • 3 • 5 What prime factors do the numbers have in common? Multiply those numbers. The GCF is 2 • 3 = 6 6 is the largest number that can go into 42 and 60!

  8. Find the GCF of 40 and 48. 40= 2 • 2 • 2 • 5 48= 2 • 2 • 2 • 2 • 3 What do they have in common? Multiply the factors together. GCF = 8

  9. What is the GCF of 48 and 64? • 2 • 4 • 8 • 16
