We try dividing 13071240 by 19, we get 687960.

We try dividing 687960 by 19 again, but we get a decimal fraction.

We try dividing 687960 by 18, and we get 38220.

We try dividing 38220 by 18 again, but we get a decimal fraction.

We try dividing 38220 by 17, but we get a decimal fraction.

We try dividing 38220 by 16, but we get a decimal fraction.

We try dividing 38220 by 15, and we get 2548.

No use to divide 2548 by 15 again, for no multiple of 15 ends in 8.

We try dividing 2548 by 14, and we get 182.

We try dividing 2548 by 14 again, and we get 13.

So their ages are 13, 14, 14, 15, 18, and 19  

The sum of their ages is 13+14+14+15+18+19 = 93
