Bob says he has 3 kids the product of their ages 72 the sum of the ages of his children my youngest child is called Justice how old are they

72=2*2*2*3*3

Children ages and sums:

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

If we know the sum and that sum is only one, we don't need the information about youngest child so sum is 14. Children ages couldn't be 3, 3 and 8 because there is only one youngest child. That means children ages are: 2, 6, 6.
