They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
The first 10 multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30.
The first few multiples of nineteen are:1938577695114133152171190209
Take the first number. Add it to itself. Keep adding that number to the total three more times. The first five nonzero multiples of 9 are 9, 18, 27, 36, and 45. Put another way, let each number equal x. The first five nonzero multiples of x are 1x, 2x, 3x, 4x and 5x.
