A number which is divisible by 2,3 and 9?
so the least common multiple of 2,3, 9
would be 18
My guess would be :
The neighbour brought 1 more cow for the 3 boys
So there would be 18 cows altogether
Oldest son got 18/2 = 9 whole cows
Middle son got 18/3 = 6 whole cows
and Youngest son got 18/9 = 2 whole cows
9+6+2 adds up to 17 cows
So the neighbour then takes his cow back
Is that it ? O_O
