Sabemos que muitos cometas passam próximos à órbita terrestre, em períodos regulares. Um cometa A passa de 15 em
15 anos, enquanto um cometa B passa de 20 em 20 anos e um cometa C, de 30 em 30 anos. Esses três cometas
passaram por aqui em 1998. Nessas condições, EM QUE ano os cometas A, B e C passarão juntos, novamente, pela
Terra?

Faça o MMC dos valores dados:

mmc de 15 e 20  

15 | 20 | 2

15 | 10 | 2

15 |   5 | 3

 5 |   5 | 5

 1 |   1 | ===>  2² . 3 . 5 = 60

60 anos

Passarão juntos novamente no ano de:  

1998 + 60 = 2058
