First three common multiples of 5 and 6 are 30, 60 and 90.
Common multiples of 6 and 10 are 30, 60, 90, 120, 180, 210...
60
30, 60, 90,.......
60
It is 60.
30 and 60
The common multiples of 1 and 6 are the same as the multiples of 6. They are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, and so on.
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
All multiples of 840 are common multiples of 60 and 280
The common multiples of 2 and 6 are the infinite set of numbers that are multiples of their LCM, which is 6. So the common multiples of 2 and 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, and so on.
The common multiples of any numbers are multiples of their lcm. The lcm of 2, 3, 4, 5 & 6 is 60 Thus the next four common multiples are 2 x 60, 3 x 60, 4 x 60 & 5 x 60 which are 120, 180, 240 & 300
