The product of 3 brothers' ages is 567. Two are twins.

How old is the other one?

The only way to finish with 7 is to have either the twins' ages product finish 1 and the other brother's age finish with 7, or vice versa, or have a 3 and a 9. By trying different combinations we find that:

The twins ages are 9. 9*9=81
The other brother is 7 years old. 81*7=567.
