They are all multiples.
the common multiples are most all of the multiples of 8
All multiples of 840 are common multiples of 60 and 280
All numbers have common multiples.
Common multiples of 9 and 10 are all of the multiples of 90.
Common Multiples of 8:8,16,24,32,40,48,56,64,72,80,88 and 96 Common Multiples of 12:12,24,36,48,60,72,84 and 96
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
All multiples of 36 are also multiples of 12.
All of the multiples of 8 are.
12 and all its multiples.
There are infinitely many common multiples of 6 and 8. The least common multiple of them is 24. After that, all of the multiples of 24 (i.e., 48, 72, 96, etc.) are the common multiples of 6 and 8.
