15 30 45 60 75 90
15, 30 & 45
The common multiples of 3 and 15 from 1 to 100 are 15, 30, 45, 60, 75, 90
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
The only number between 3 and 45 which is a factor of 3 is 3. There are several multiples of 3 beyond this.

15, 30, 45, 60, 75, 90
45 multiples of 2 plus 30 multiples of 3 minus 15 multiples of 6 equals 60 numbers
30, 45, 60
15, 45, 60 and so on.
90. All numbers that are multiples of 3, 5 & 9 are multiples of their lowest common multiple lcm(3, 5, 9) = 45 → multiples of 45 between 49 and 95 is 2 x 45 = 90.
The first 3 common multiples of 4 and 5 are: 20, 40, and 60.
15, 30, 45
