Answer 1

$a)8 = {2}^{3} \\ 24 = {2}^{3} \times 3 \\ M.C.M.(8,24) = {2}^{3} \times 3 = 24 \\ M.C.D.(8,24) = {2}^{3} = 8$

$b)15 = 3 \times 5 \\ 14 = 2 \times 7 \\ M.C.M.(15,14) = 2 \times 3 \times 5 \times 7 = 210 \\ M.C.D.(15,14) = 1$

$c)20 = {2}^{2} \times 5 \\ 30 = 2 \times 3 \times 5 \\ M.C.M.(20,30) = {2}^{2} \times 3 \times 5 = 4 \times 3 \times 5 = 60 \\ M.C.D.(20,30) = 2 \times 5 = 10$

$d)16 = {2}^{4} \\ 18 = 2 \times {3}^{2} \\ M.C.M.(16,18) = {2}^{4} \times {3}^{2} = 16 \div 9 = 144 \\ M.C.D.(16,18) = 2$

$e)12 = {2}^{2} \times 3 \\ 18 = 2 \times {3}^{2} \\ M.C.M.(12,18) = {2}^{2} \times {3}^{2} = 4 \times 9 = 36 \\ M.C.D.(12,18) = 2 \times 3 = 6$

$f)15 = 3 \times 5 \\ 30 = 2 \times 3 \times 5 \\ M.C.M.(15,30) = 2 \times 3\times 5 = 30 \\ M.C.D.(15,30) = 3 \times 5 = 15$

$h)20 = {2}^{2} \times 5 \\ 48 = {2}^{4} \times 3 \\ M.C.M.(20,48) = {2}^{4} \times 3 \times 5 = 16 \times 3 \times 5 = 240 \\ M.C.D.(20,48) = {2}^{2} = 4$
