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 common multiples of 3 and 7 are 21, 42, 63 and so on.
42 is the LCM of 3, 6 and 7. All multiples of 42 are multiples of 3, 6 and 7
The multiples of 3 up to 50 are: 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48
15, 30, and 45 .
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.
52 and 56 are multiples of 4 and have 1, 2 and 4 in common. 54 and 57 are multiples of 3 and have 1 and 3 in common.
The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
Common multiples of 3 and 7 are numbers that are divisible by both 3 and 7. To find the common multiples up to 100, we need to find numbers that are multiples of both 3 and 7. The common multiples of 3 and 7 up to 100 are 21, 42, 63, and 84. These numbers are multiples of both 3 and 7 within the range of 1 to 100.
15, 30, and 45
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.
