There is an infinite number of common multiples for 3 and 5. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 3 and 5 is 15.
There are infinitely many common multiples of 3, 5 and 7, each one 105 larger than the previous one. Or to put it another way: the common multiples of 3, 5 and 7 are the multiples of their lowest common multiple which is 105. ie their common multiples are all the multiples of 105, of which there is no end - there is an infinite number of multiples of 105 (or any other number [except zero]).
60 and its multiples
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
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.

To start with the 3 common multiples of 5 they are........10,15,and 25the 3 common multiples of 3 are.........15,30,and 45hope this helped=)
1, 3, 5 and 15
60 and its multiples
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
The common multiples of 2, 3, and 5 are numbers that are divisible by all three of these numbers. To find the common multiples, we need to identify the multiples of each number and then find the numbers that appear in all three lists. The common multiples of 2, 3, and 5 are 30, 60, 90, 120, and so on, as these numbers are divisible by 2, 3, and 5 simultaneously.
The first two common multiples of 235 is 5 and 47.
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
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.
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.
90. All numbers that are multiples of 3, 5 & 9 are multiples of their lowest common multiple lcm(3, 5, 9) = 45 → multiples of 45 between 49 and 95 is 2 x 45 = 90.
The two common multiples of three and five are: 15 and 30 ^-^
