840
120 and all the multiples of 120.
120 and all its multiples.
They would be all the multiples of 360, which is an infinite list.
All multiples of 120 are multiples of both 40 and 24, because 120 contains all the factors of 40 (23*5) and 24 (23*3). Some examples of multiples are 120, 240, 360, and 600.
the common multiples are most all of the multiples of 8
All multiples of 120, which is an infinite number.
120, 1200, 12000, 120000 and 1200000000000 are all multiples of 12.
Not all multiples of 40 are multiples of 80. Only the even multiples of 40 are also multiples of 80. The odd multiples, e.g. 40, 120, 200, 280, and 360, are not multiples of 80.
They are infinite, starting with these: 120, 240, 360, 480, 600, 720 . . .
All multiples of 12, such as 120, 600, 660.
LCM(8, 5, 15) = 120 so the answer is 120 and all its multiples.
The common multiples of 3,4, and 10 would be all the multiples of 60. 60, 120, 180, 240... all the way to 6000.
