220, 440, 660 and so on.
the common multiples of 20 and 25 is 100 (through 100)
2 and 4 are common multiples of the numbers 14 and 20
There is an infinite number of common multiples for 4 and 20. A common multiple of any two numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
There is an infinite number of common multiples for 12 and 20. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
20 and 30 could be two such numbers.
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 is an infinite number of common multiples for 20 and 32. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple of 20 and 32 is 160.
The least common multiple of the numbers 20 and 28 is 140.
There is an infinite number of common multiples for 20 and 30. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
Suppose the question is, what are the common multiples of 16 and 20? One way to answer this question is to start listing the multiples of each of the numbers and look for the numbers that are on both lists.Multiples of 16 are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, ...Multiples of 20 are 20, 40, 60, 80, 100, 120, 140, 160, 180, ...If we continued this list there would be more numbers in common. In fact, all multiples of 80 would be on both lists.Therefore, the common multiples of 16 and 20 are 80, 160, 240, 320, 400, .... The Least Common Multiple is 80.
You need at least two numbers to find an LCM.
