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

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.

Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.

There are 30 two-digit multiples of 3 plus 18 two-digit multiples of 5 minus 6 two-digit multiples of both. Answer: 42

Both numbers are multiples of 5

6, 12, 18, 24, 30

Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7

15

5 and 25

Since 3 and 5 are both prime numbers, the only common factor of the two numbers is 1. Perhaps you are thinking of common multiples, the first two common multiples of the two numbers are 15 and 30.

15, 30, 45, 60

It is not possible it has to be an even number.Plus it has no times or division numbers.
