To find the Greatest Common Factor (GCF) of 9, 15, and 18, you need to first factorize each number. The factors of 9 are 1, 3, and 9. The factors of 15 are 1, 3, 5, and 15. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factor among all three numbers is 3, making the GCF of 9, 15, and 18 equal to 3.
15 - 9 = 6
GCF = 3 LCM = 18 Factors of 9: 1, 3, 9 Factors of 6: 1, 2, 3, 6 Multiples of 9: 9, 18 Multiples of 6: 6, 12, 18
