WebTo calculate the LCM of 21 and 28 by the division method, we will divide the numbers(21, 28) by their prime factors (preferably common). The product of these divisors gives the LCM of 21 and 28. Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 21 and 28. WebHighest Common Factor of 28,21 is 7. Step 1: Since 28 > 21, we apply the division lemma to 28 and 21, to get. Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 7 and 21, to get. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 28 and 21 is 7.
