WebDetailed Answer: The Greatest Common Factor (GCF) for 6, 12 and 15, notation CGF (6,12,15), is 3. Explanation: The factors of 6 are 1,2,3,6; The factors of 12 are 1,2,3,4,6,12; The factors of 15 are 1,3,5,15. So, as we can see, the Greatest Common Factor or Divisor is 3, because it is the greatest number that divides evenly into all of them. Prime factorization of 9 and 15 is (3 × 3) and (3 × 5) respectively. As visible, 9 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 9 and 15 is 3. Ver mais HCF of 9 and 15 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. 1. Step 1: Divide15 (larger … Ver mais As per the Euclidean Algorithm, HCF(X, Y) = HCF(Y, X mod Y) where X > Y and mod is the modulooperator. Here X = 15 and Y = 9 1.
