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.
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.
That's an infinite list.
First of all unless you go into decimals, there are only three multiples of 9 and they are 1,3,and 9.

Traditionally, 0 is not listed among the first five multiples. To avoid confusion, questions will frequently say, "List the first five non-zero multiples of 9." The answer is 9, 18, 27, 36 and 45. If 0 is included, put it first.

The first 5 multiples of 5 are: 5, 10, 15, 20, 25 The first 5 multiples of 9 are: 9, 18, 27, 36, 45 The first 5 multiples of both 5 and 9 are: 45, 90, 135, 180, 225
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18. They are the products of 3 and the nonzero integers 1, 2, 3, 4, 5, and 6.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
0 isn't the first multiple of 9.
9, 18, 27, 36, 45
3, 6, 9, 12, 15 The mean is 9.
