excuse me but my english is so bad
72=2*2*2*3*3

72=2*2*18 (sum 22)
72=2*3*12 (sum 17)
72=2*4*9 (sum 15)
72=2*6*6 (sum 14)
72=3*3*8 (sum 14)
72=3*4*6 (sum 13)

due to the fact mrs raines needed more info, only "2*6*6" and "3*3*8" are posible.
"her eldest son" means "no twins"
so the solution is 8,3,3
