Answer by elima(1433)   (Show Source):
You can put this solution on YOUR website! First list divisors that 6 and 15 can go into;
30, 60, 90, 120, etc.
Now look at the integers given to you;
2, 5, 9, 10, 30
Which one of these can not go into ALL of the divisors of 6 and 15?
It would be c. 9
Hope you understand
