WebUsing the common factor method, find the HCF of: 25 and 20 The HCF of 20 and 25 is 5. To calculate the HCF (Highest Common Factor) of 20 and 25, we need to factor each … WebIn the prime factorisation method, we need to express the given numbers as the product of prime factors to find the Highest Common Factor. 20 = 2 × 2 × 5 28 = 2 × 2 × 7 36 = 2 × 2 × 3 × 3 The common prime factors of 20, 28 and 36 are 2 and 2. Therefore, HCF (20, 28, 36) = 2 × 2 = 4 HCF of 20, 28 and 36 by Long Division Method
Find the HCF of 20, 24, 36. - Vedantu
WebThe procedure to find the HCF of number by division method is as follows: First, consider the given numbers and find which is large and small then divide the large number by small number. In the second step, … WebStep 1: Since 25 > 20, we apply the division lemma to 25 and 20, to get 25 = 20 x 1 + 5 Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 5 and 20, to get 20 = 5 x 4 + 0 The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 20 and 25 is 5 Notice that 5 = HCF (20,5) = HCF (25,20) . global connect sbf
