• First convert the given numbers into fractional parts . Then LCM=LCM(NUMERATOR)/HCF(DENOMENATOR) HCF=HCF(NUMERATOR)/LCM(DENOMENATOR) LCM=42 HCF=0.042

• Let’s take two fractions strong(a/b)/strong and strong(c/d)./strongbr /To find LCM and HCF of strong(a/b)/strong and strong(c/d) /strongthe generalized formula will be:br /strongH.C.F/strong = emH.C.F of numerators/em / emL.C.M of denominators/embr /strongL.C.M/strong = emL.C.M of numerators /em/ emH.C.F of denominatorsbr /so LCM will be 42br /HCF will be 0.042/em

• Initially multiply by 1000 each no so the numbers will be =4200,42000,420,42br /LCM (4200,42000,420,42) = 42000     br /we multiplied the number by 1000 so answer should be divided by 1000 implies lcm = 42br /HCF of rational number = HCF of numerator / lcm of numerator = 0.042

• Convert them to fractions(p/q) and then do LCM of numerators divide with HCF of denominators in the first case.viceversa u get hcf

• The simplest way to solve this kind of questions is to convert these decimals into fractions and it will become easier. And solving this question you will get 42 as LCM
