    72 has the following factors 2*2*2*3*3

    With these factors the following age combinations can be made:
    1+1+72 = 74
    1+2+36 = 39
    1+3+24 = 28
    1+4+18 = 23
    1+6+12 = 19
    1+8+9 = 18
    2+2+18 = 22
    2+3+12 = 17
    2+4+9 = 15
    2+6+6 = 14
    3+3+8 = 14
    3+4+6 = 13

    Only two of them have the same sum: 2,6,6 and 3,3,8
    With all the other combinations Jason would have known the answer with only the first two hints.
    The last hint says that John has an oldest son.
    With the ages 2, 6 and 6 John would have two “oldest sons”

    So the correct answer is 3, 3, and 8.
