Any multiple of 300
30, 60, 90 and so on. 36, 72, 108 and so on. 50, 100, 150 and so on. Common multiples include 900, 1800, 2700 and so on.
150
The Least Common Multiple of 20 and 50 is 100. Multiples of 20 are 20, 40, 60, 80, 100, and so on. Multiples of 50 are 50, 100, 150, 200, 250, and so on. So the least common multiple of the numbers 20 and 50 is 100.
This needs more information. Generally, questions like this read, "What are the common multiples (of certain numbers) that are under 50?" Example: 3 and 5 The common multiples of 3 and 5 that are under 50 are 15, 30 and 45.
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.
900
Any multiple of 150
The common multiples of 2 and 5 to 100 are: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
the greatest common factor is 50. 50 x 1 = 50. 50 x 2 = 100. there's no limit to the multiples, it is infinite.
Multiples of 9 up to 100 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99. Multiples of 10 up to 100 are 10, 20, 30, 40, 50, 60, 70, 80. 90, 100. The only common multiple up to 100 of 9 and 10 is 90.
Multiples of 25 include 25, 50, 75, 100, 125 and so on. For them to be common, they need to be compared to another set of multiples.
15, 30, and 45 .
