Question

Find the LCM of 72 and 126 by prime factorization method.​

Answer 1

Given: LCM (72, 126) = 504 To Find: HCF (72, 126) We use the formula L.C.M (a,b) × H.C.F (a,b) = Product of two numbers (a×b) LCM (72, 126) × HCF (72, 126) = 72 × 126 ⇒ 504 × HCF (72, 126) = 72 × 126 [LCM(72,126)=504] Read more on Sarthaks.com - https://www.sarthaks.com/920577/if-lcm-72-126-504-find-hcf-72-126
