CALCULAR EL M.C.M DE 25,40 DE 18,12 CALCULAR EL M.C.D DE 36,24​

Answer 1

$25 = {5}^{2} \\40 = {2}^{3} \times 5 \\ M.C.M.(25,40) = {2}^{3} \times {5}^{2} = 8 \times 25 = 200$

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

$36 = {2}^{2} \times {3}^{2} \\ 24 = {2}^{3} \times 3 \\ M.C.D.(36 , 24) = {2}^{2} \times 3 = 4 \times 3 = 12$
