If the numbers are multiples of 2, 3, and 5, they are multiples of 2 x 3 x 5 = 30. Here are some multiples of 30:
30, 60, 90, 120, 150, 180, 210, 240, 270, 300, ...
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.
Multiples of 1- 1, 2 3, 4 ,5, 6, 7, 8, 9, 10-- Like counting Multiples of 2- 2,4,6,8,10,12, ect. Multiples of 3- 3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54, Multiples of 4- Multiples of 5- Multiples of 6
30 and all multiples of 30 have factors including 2, 3, and 5.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
2, 3, and 5 are factors of 30 and all multiples of 30.

The numbers 3, 5, 7, 9, 11, 13, 15, 17, and 19 are not multiples of 2.

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.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
