Porfís ayudenme

Answer 1

60:2                      90:2
30;2                      45:3
15:3                      15:3
  5:5                        5:5
  1                           1

60= 2^2 * 3 *5       90 = 2 * 3^2 *5
DCM se multiplican los factores comunes con su menor exponente
DCM = 2 * 3 * 5
DCM =30

100:2                      15:3
  50:2                        5:5
  25:5                        1
    5:5
    1
DCM = 5

40:2                           60:2                      100:2
20:2                           30:2                        50:2
10:2                           15:3                        25:5
  5:5                             5:5                          5:5
  1                                1                             1

DCM =2^2 * 5
DCM =20
