WebFind the HCF and LCM of 18 and 45 by prime factorisation method. Express 18 and 45 as product of primes. 18=233=232 45=335=325 HCF of 18 and 45=33=9. Get Study. Get … WebMar 12, 2024 · So, we can say that the Highest Common Factor (HCF) of 18 and 45 can be obtained as: ⇒ HCF ( 18, 45) = 3 × 3 = 9 Therefore, the HCF of 18 and 45 is 9. To obtain the LCM of 18 and 45, we will multiply all the factors of 18 and 45 (without repeating the common factors in individual prime factorization).
HCF of 18, 54 and 81 How to Find HCF of 18, 54, 81? - Cuemath
WebThere are three commonly used methods to find the HCF of 45 and 180. By Long Division By Listing Common Factors By Prime Factorisation If the HCF of 180 and 45 is 45, Find its LCM. HCF (180, 45) × LCM (180, 45) = 180 × 45 Since the HCF of 180 and 45 = 45 ⇒ 45 × LCM (180, 45) = 8100 Therefore, LCM = 180 WebFollow the below steps to find the HCF of given numbers with Euclid’s Division Lemma: Step 1: Apply Euclid’s division lemma, to a and b. So, we find whole numbers, q and r such that a = bq + r, 0 ≤ r < b. Step 2: If r = 0, b is the HCF of a and b. If r ≠ 0, apply the division lemma to b and r. Step 3: Continue the process until the ... children\u0027s hospital pcp
