Explicație pas cu pas:
7.
Deimpartit = Impartitor x Cat + Rest
n = 3C1 + 2
n = 4C2 + 2
n = 5C3 + 2
n - 2 = 3C1
n - 2 = 4C2
n - 2 = 5C3
n - 2 = cmmmc (3, 4, 5) = 3*4*5 = 60
n = 60 + 2 = 62

n = 3C1 + 2
n = 4C2 + 3
n = 5C3 + 4
n + 1 = 3C1 + 2 + 1 = 3C1 + 3 = 3(C1 + 1)
n + 1 = 4C2 + 3 + 1 = 4C2 + 4 = 4(C2 + 1)
n + 1 = 5C3 + 4 + 1 = 5C3 + 5 = 5(C3 + 1)
n + 1 = cmmmc (3, 4, 5) = 60
n = 60 - 1 = 59
