Look at the prime decompositions of all three numbers:
3 = 3
5 = 5
9 = 3 * 3
Then take the "union" of all these compositions, i.e. the minimum number of 3s you need is 2, the minimum number of 5s you need is 1 and for all other primes it is 0. Therefore the smallest number divisible by all numbers is 3*3*5 = 45.
