20 pinkgal333:20, 40, 60 are all common multiples.
5, 10, 15, 20
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.
There are infinitely many multiples of 10 so it is far from clear what you mean by "all 5" multiples. Any integer which ends in a 0 is a multiple of 10.
No, 5x2 = 10 which does not end in 5. All multiples of 5 will always end in a 5 or 0
Because 20 is a multiple of 4. All multiples of 20 are also multipples of 2, 5 and 10
Since 10 is a multiple of 5, all multiples of 10 are multiples of 5.
False, all multiples of 10 end in 0. All multiples of 5 end in 5 or 0.
All of them are.
20 pinkgal333:20, 40, 60 are all common multiples.
The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
The first 5 multiples of 4 are 4, 8, 12, 16, then 20.
5, 10, 15, 20 :)

Since 10 is a factor of 20, all multiples of 20 are multiples of 10. This is also true of 1, 2, 4 and 5.
