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.
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also 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 :)
