Question

Find the HCF and LCM of $\frac{8}{9},\frac{10}{27}and\frac{16}{81}$.

Answer 1

$\frac{8}{9}=\frac{2\times 2\times 2}{3\times 3}$

$\frac{10}{27}=\frac{2\times 5}{3\times 3\times 3}$

$\frac{16}{81}=\frac{2\times 2\times 2\times 2}{3\times 3\times 3\times 3}$

L.C.M of $\frac{8}{9},\frac{10}{27}$ and $\frac{16}{81}=\frac{2\times 2\times \times 2\times 2\times 5}{3\times 3\times 3\times 3}=\frac{80}{21}$

H.C.F of $\frac{8}{9},\frac{10}{27}$ and $\frac{16}{81}=\frac{2}{3}$
