432 = 2^4*3^3

112 = 2^4*7

252 = 2^2*3^2*7

72 = 2^3*3^2

45 = 3^2*5

24 = 2^3*3

30 = 2*3*5

76 = 2^2*19

48 = 2^4*3

Explicație pas cu pas:

28 = [2, 2, 7]

1260 = [2, 2, 3, 3, 5, 7]

288 = [2, 2, 2, 2, 2, 3, 3]

1890 = [2, 3, 3, 3, 5, 7]

2268 = [2, 2, 3, 3, 3, 3, 7]

450 = [2, 3, 3, 5, 5]

1300 = [2, 2, 5, 5, 13]

216 = [2, 2, 2, 3, 3, 3]

300 = [2, 2, 3, 5, 5]

432 = [2, 2, 2, 2, 3, 3, 3]

112 = [2, 2, 2, 2, 7]

252 = [2, 2, 3, 3, 7]

72 = [2, 2, 2, 3, 3]

45 = [3, 3, 5]

24 = [2, 2, 2, 3]

30 = [2, 3, 5]

76 = [2, 2, 19]

48 = [2, 2, 2, 2, 3]
