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.
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
A common multiple is a multiple that two or more given numbers have in common. 16 is not a common multiple of 7 and 8. 16 is a common multiple of 4 and 8. So, it depends on the numbers for which you are trying to find a common multiple.
You need at least two numbers to find a common multiple.
to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers
You need at least two numbers to find a common multiple.
The Least Common Multiple (LCM) is 30.
You need at least to numbers to find a least common multiple.
The Least Common Multiple (LCM) is 15.
To find a common multiple - you need to have something to compare it to ! For example, the least common multiple of 2 & 3 is 6 !
It is impossible to find the highest common multiple of any set of numbers, because there is no end to numbers. However, it is possible to find the least common multiple of a set of numbers. The least common multiple of 300 and 882 is 220,500.
It is infinite but the lowest common multiple is 4500
Any multiple of 40.
