  14. Name a Common Factor of 10 and 25? 1, 5, 10

  15. Name a Common Factor of 3 and 4? 1

  16. Simplest Form • When the only common factor of the numerator and denominator is 1, the fraction is in simplest form. 3 1 3 ÷ = 4 1 4

  17. Greatest Common Factor • The greatest common factor is the largest factor between two numbers. 12 = 1, 2, 3, 4, 6, 12 18 = 1, 2, 3, 6, 9, 18

  18. What is the Greatest Common Factor? 8 = 1, 2, 4, 8 12 = 1, 2, 3, 4, 6, 12

  19. What is the Greatest Common Factor? 8 = 1, 2, 4, 8 14 = 1, 2, 7,14

  20. What is the Greatest Common Factor? 6 = 1, 2, 3, 6 18 = 1, 2, 3, 6, 9, 15

  21. What is the Greatest Common Factor? 6 = 1, 2, 3, 6 12 = 1, 2, 3, 4, 6, 12

  22. What is the Greatest Common Factor? 8 = 1, 2, 4, 8 16 = 1, 2, 4, 8, 16

  23. What is the Greatest Common Factor? 8 = 1, 2, 4, 8 10 = 1, 2, 5, 10

  24. What is the Greatest Common Factor? 3 = 1, 3 6 = 1, 2, 3, 6

  25. What is the Greatest Common Factor? 4 = 1, 2, 4 6 = 1, 2, 3, 6

  26. What is the Greatest Common Factor? 7 = 1, 7, 21 = 1, 3, 7, 21

  27. What is the Greatest Common Factor? 15 = 1, 3, 5, 15 24 = 1, 2, 3, 8, 12, 24

  28. How to Find the Simplest Form of a Fraction • Find the greatest common factor of the numerator and the denominator and divide both the numerator and the denominator by that number. 12 6 2 ÷ = 18 6 3
