They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
First three common multiples of 5 and 6 are 30, 60 and 90.
That's not going to work. Multiples of 5 end in 5 or 0. With three numbers, one of those would have to repeat.
