find the HCF 12,16 and 18 by prime factorization method​

Answer 1

Answer:

1. How to Find the HCF of 12, 16 and 18 by Prime Factorization? To find the HCF of 12, 16 and 18, we will find the prime factorization of given numbers, i.e. 12 = 2 × 2 × 3; 16 = 2 × 2 × 2 × 2; 18 = 2 × 3 × 3. ⇒ Since 2 is the only common prime factor of 12, 16 and 18. Hence, HCF(12, 16, 18) = 2.
