3,4,6
The eldest son has started piano classes it means he must be minimum age of 6 years.
And, 3*4*6=72
Then 3+4+6=13 it means birth date of Jacky
Factorizing 72 = 2*2*2*3*3=separate three parts
That means eldest son must be 6 years .so cut 2 and 3.
And then left 2,2,3 a son must be smaller than another so one is 4 years and one is 3 years.
