WebSince the divisor at this stage is 6, the HCF of 6 and 12 is 6. Notice that 6 = HCF (12,6) . We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma. Step 1: Since 21 > 6, we apply the division lemma to 21 and 6, to get. Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get. WebStep 1: Find the prime factors of the given number. Step 2: List the common prime numbers. Step 3: Multiply the common prime number. The result is the HCF of the number. Therefore, the HCF of 12 and 15 is as follows: Step 1: Find the prime factors of the given number. Prime factor of 12 = 2 × 2 × 3. can\u0027t give control in teams
