15, 30, and 45
The first common multiples of 5, 3, and 8 are found by listing out the multiples of each number and finding the least common multiple. The multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, and so on. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and so on. The multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, and so on. The first common multiples of 5, 3, and 8 are 24 and 48.
The Least Common Multiple (LCM) of (15,30,50) is 150
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.
The multiples of 40 are 40, 80, 120, 160, 200, 240, 280, 320, and so on. The multiples of 50 are 50, 100, 150, 200, 250, 300 350, 400, 450, 500, and so on. The common multiples of 40 and 50 are 200, 400, 600 and so on.
150
250
To find the numbers between 10 and 50 that are multiples of both 3 and 5, we need to find the numbers that are multiples of the least common multiple of 3 and 5, which is 15. The multiples of 15 between 10 and 50 are 15, 30, and 45. Therefore, there are 3 numbers between 10 and 50 that are multiples of both 3 and 5.

GCD: 5 LCM: 50
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.
This is not enough information. Determining a least common multiple requires two or more numbers.
Since 50 is a multiple of 5, it is automatically the LCM of this problem.
15, 30, and 45 .
Least Common Multiple (LCM) for 10 25 is 50
The LCM of 5, 10, and 15 is 30. The multiples of 5 are 5, 10, 15, 20, 25, 30, and so on. The multiples of 10 are 10, 20, 30, and so on. The multiples of 15 are 15, 30, and so on. So the LCM of 5, 10, and 15 is 30.
