Multiples of 10 include any number ending in zero. For them to be common, they need to be compared to another set of multiples.
all the multiples of 10 are 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 230 240 250 260 270 280 290 300...ect.
240, 250, 260.
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
Common denominators. These are called "common multiples". For example, multiples of 4 are: 4,8,12,16,20,24 ... . Multiples of 6 are: 6,12,18,24,30,36 ... . The numbers on both lists are the common multiples and they include: 12,24,36, ... . Specifically, the smallest number in any such list of common multiples (12 in this example) is known as the Least (or Lowest) Common Multiple or LCM.
There a four: 250, 500, 750, 1000
The factors of 250 are 1, 2, 5, 10, 25, 50, 125, and 250. The multiples of 250 are 250, 500, 750, 1000, 1250, 1500, 1750, 2000, 2250, 2500, and so on.

1, 2, 5, 10, 25, 50, 125, 250. <those are factors Multiples of 250 would be 250, 500, 750, 1000, 1250, 1500, 1750, 2000, etc. edit: my bad
1 x 250, 2 x 125, 5 x 50, 10 x 25 = 250
240, 250, 260.
None of the positive common divisors of those numbers are multiples of 10.
1, 2, 5, 10, 25, 50, 125, 250.
2, 4, 10, 20, 50, 100, 250, 500
Multiples of 125 are 125, 250, 375, 500, etc. Multiples of 50 are 50, 100, 150, 200, 250, etc. Common multiples of 125 and 50 are 250, 500, 750, 100, etc.
25, 50, 75, 100, 125, 150, 175, 200, 225, 250.
