Thus the product of lcm and hcf is not a functionof the product of the three numbers. 7. HCF (Highest common Factor): HCF is also known as Greatest common divisor, HCF of two numbers is the largest positive integer that divides both the numbers. LCM HCF Product Property: Product of LCM and HCF equals product of . Solution: LCM = 2 × 2 × 5 = 20 Thus the LCM of 10 and 20 is 20. 48. Find the LCM of decimal . Application: Given -. In this case is 3. LCM of two numbers = 48. We observe that, LCM (12, 18) = 36, GCD (12, 18) = 6 . (A,B) = A x B Use this function to get LCM of first two numbers of array, then result of LCM will be used to . If one number is 20 then other may be (A) 100 (B) 50 (C) Both A and B (D) none of the above. LCF 2. 5 x 47 + 3 = 238. In this case, 2 for a and 3 for b. 12. 4 x 238 + 2 = 954. So we got. HCF of two numbers = 6. For any number of numbers, LCM is always an integral multiple of HCF but this 'integer' in not static like 1 or 2 or 3 and so on but it varies from situation to situation. Moving on to the LCM finding part: There exists a relation between LCM and GCD. Hence, HCF of (50, 80) = 2 × 5. If k = 2, number = (840 × 2) + 3 = 1683 which is divisible by 9. Step 1: Divide 4 (larger number) by 3 (smaller number). H.C.F. The LCM is 168. HCF × LCM = Product of the two numbers Following are the relations between HCF and LCM of two numbers: The product of HCF and LCM of any two given natural numbers is equal to the product of the given numbers. 4. LCM(66, 45) = 2*3*3*5*11 = 990 So the pair of 100 and 45 has the smallest LCM. The formula of HCF and LCM is nothing but the relationship between HCF and LCM.
