What is the HCF and LCM of 275 and 825 and 4125 - Brainly
WebWe can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma. Step 1: Since 315 > 45, we apply the division lemma to 315 and 45, to get. 315 = 45 x 7 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 45 and 315 is 45. Notice that 45 = HCF(315,45) . WebHCF and LCM Examples Example 1: Find the Highest Common Factor of 25, 35 and 45. Solution: Given, three numbers as 25, 35 and 45. We know, 25 = 5 × 5 35 = 5 × 7 45 = 5 × 9 From the above expression, we can say 5 is the only common factor for all three numbers. Therefore, 5 is the HCF of 25, 35 and 45.
