Well, honey, common multiples of 5 and 10 are numbers that both 5 and 10 can divide evenly into. So, grab your calculator and start counting by 10s until you hit a number that is also divisible by 5. Spoiler alert: the first few common multiples are 10, 20, 30, 40... you get the idea. Happy math-ing!
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, ... Multiples of 5: 5, 10, 15, 20, 25, 30, ... Multiples of 10: 10, 20, 30, 40, 50, ... So the LCM (Least Common Multiple) is 10.
Multiples of 4: 4, 8, 12, 16, 20 Multiples of 10: 10, 20 Therefore, the answer is 20. (:
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.
The two smallest multiples of 10 are 10 and 20. For them to be common, they would need to be compared to another set of multiples.
They are 10 and 20
20 pinkgal333:20, 40, 60 are all common multiples.
Multiples of 10 include any number ending in zero. For them to be common, they need to be compared to another set of multiples.

20, 40 and 60
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.
10 and 20
The LCM is 60
10, 20, 30.
10, 20, 30
