It's a multiple of 5, a multiple of 6 (since it's between twin primes), and less than 50. The only possibility is 30. To check:
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30

Six has four factors and is in between the twin primes 5 and 7.
1617 is not a prime number. The sum of its digits is a multiple of 3, so 3 is one of its factors. A prime number has exactly two factors, 1 and the number itself, so 1617 is a composite number.
28.
It is 30.

There is no multiple of 369 between 61 and 107. A multiple is a number that the figure can divide into. The lowest number 369 can divide into is 369. Numbers that divide into it are its factors. None of its factors are between 61 and 107 though.
A number that has exactly an odd number of factors is a power of another number. A number between 10 and 30 that is a power is 16. It is 24 (as well as 42) and its factors are 1, 2, 4, 8, and 16.
No number between 67 and 113 is a multiple of 359. It has no factors in that range either, if that is what you meant.

No number between 61 and 107 is a multiple of 41020. A multiple is a number that another number can divide into. The lowest multiple of any number is itself. You may have meant factors, which is a number that divides into a multiple of itself. In that case there is a factor of 41020 between 61 and 107. That number is 70.
A prime number has exactly two factors.
