No number has the multiples of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, but the number 80 (and all its multiples: 160, 240, 320, 400, ...) has them all as FACTORS.
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 Those which are multiples of 4 are: 4, 8, 16, 20, 40, 80
Because they are multiples of 5. All multiples of 5 have 5 as a factor, which means they are divisible by 5.
40, 80, 120, 160, 200.

All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
It is: 80 and 100
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
All the multiples of 20 cannot be listed since they are infinite in number. They start 20, 40, 60, 80, 100, ...
-15
The first 5 multiples of 4 and 20 are 20, 40, 60, 80, 100
