Question

factoriza y halla mcm dcm

28 y 42
40 y 100
81 y 216

Answer 1

28 = 2 * 2 * 7
42 = 2 * 3 * 7

mcm: 2 * 2 * 3 * 7 = 84
mcd: 2 * 7 = 14

40 = 2 * 2 * 2 * 5
100= 2 * 2 * 5 * 5

mcm: 2 * 2 * 2 * 5 * 5 = 200
mcd: 2 * 2 * 5 = 20

81 = 3 * 3 * 3 * 3
216 = 2 * 2 * 2 * 3 * 3 * 3

mcm: 2 * 2 * 2 * 3 * 3 * 3 * 3 = 648
mcd: 3 * 3 * 3 = 27
