15, 30, 45, 60, 75, 90, 105, 120 honestly people you can't do these yourselves? There's a caculator on your computer you know!
There are an infinite number of multiples of any number. Therefore, it is impossible to list all the multiples of 3 and 4. A list of the first 10 multiples: Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
20=20,40,60,80,100,120,140 15=15,30,45,60,75,90,105 12=12,24,36,48,60,2,84 8=8,16,24,32,40,48,56
6- 1,2,3,6 8- 1,2,4,8
The multiples of 2 between 7 and 15 are 8, 10, 12, and 14.
Sum of the first 15 positive integers is 15*(15+1)/2 = 120 Sum of the first 15 multiples of 8 is 8*120 = 960
I believe that 120 is the LCM. All you have to do is list the multiples of 15 until you get a number that is divisible by 8.
8, 16, 24, 32
It is 120.

4, 8, 12, 16, 20
88, 176, 264

The first 5 multiples of 4 are 4, 8, 12, 16, then 20.
120 and all its multiples.
That's an infinite list. All the multiples of 8 are composite.
