hcf and lcm

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
