WebHCF of 3 and 15 by Long Division. HCF of 3 and 15 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 15 (larger … WebThe variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 21,24,27. This is how to do it. Step 1: The first step is to use the division lemma with 24 and 21 because 24 is greater than 21. 24 = 21 x 1 + 3. Step 2: Here, the reminder 21 is not 0, we must use division lemma to 3 and 21, to get. 21 = 3 x 7 + 0

WebMar 29, 2024 · HCF of 3 Numbers Formula Here is a formula to calculate the HCF of 2 or more fractions: HCF (fractions) = HCF (all no in numerator) / LCM (all no in denominator) … WebStep 1: Since 21 > 18, we apply the division lemma to 21 and 18, to get. 21 = 18 x 1 + 3. Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 3 and 18, to get. 18 = 3 x 6 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 18 and 21 is 3.
WebCalculator Use. The Least Common Multiple ( LCM) is also referred to as the Lowest Common Multiple ( LCM) and Least Common Divisor ( LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30. WebSteps to find GCF.
