To find common multiples of two or more numbers, you can list the multiples of each.4, 8, 12, 16, 20, 24, 28, 32, 26, 40, 445, 10, 15, 20, 25, 30, 35, 40, 4520 and 40 are the common multiples that are listed. 20 is the Least Common Multiple (LCM).
Any multiple of 40.
Here is one example: 20, 40, 60, 80, 100, 120, 140, 160, 180.
That's an infinite list.
20 pinkgal333:20, 40, 60 are all common multiples.
20, 40
The answer is 40 because 20x2=40 and 5x8=40.
List the multiples. For 8: 8, 16, 24, 32, 40 For 10: 10, 20, 30, 40 So the least common multiple is 40.
20, 40 and 60
20, 40, 60, 80 and so on.
They are: 20, 40 and 60
The least common multiple (LCM) of 5 and 8 is 40. This is the smallest positive integer that is a multiple of both numbers. To find it, you can list the multiples of each: the multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, and the multiples of 8 are 8, 16, 24, 32, 40. The first common multiple is 40.
