Relation Between HCF and LCM - Definitions, and Formulas - BYJU

WebSo let us take a look at a few examples which will help you understand LCM and HCF. Example 1: Find the greatest number that will divide 400, 435 and 541 leaving 9, 10 and 14 as remainders respectively. Solution: The required number would be HCF of (400-9), (435-10) and (541-14) So the HCF (391,425,527) 391 = 17 × 23. 425 = 5 × 5 × 17. Web2. If a, b ∈ N and a b > 2 show that: lcm ( a, b) + gcd ( a, b) ≤ a b + 1. Let the lcm be l and let the gcd be g. We have to show: g + l ≤ a b + 1. I know that: g l = a b > 2.
