2 is the only number is that both a factor of 2 and a multiple of 2.
Because 2 is a factor of 4. If a number is a multiple of four, when you add that it is a multiple of 2 there is no extra information, no additional factor.

No. Any multiple of 4 is automatically also a multiple of 2. This is because 2 is, in turn, a factor of 4.
The only prime factor of 4 is 2. No prime number is a multiple of 5.
Factor of 24, but not a multiple of 8

There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.

Well, honey, a factor of 14 that isn't a multiple of 7 is 2. You see, a factor of a number divides into it evenly, while a multiple is the result of multiplying a number by an integer. So, in this case, 2 fits the bill perfectly. Hope that clears things up for ya, sugar!
The number that is a factor of 30 and a multiple of 2 is 2. A factor of a number divides it evenly without leaving a remainder, and in this case, 2 is a factor of 30 because 30 divided by 2 equals 15. Additionally, since 2 multiplied by 15 equals 30, 2 is also a multiple of 30.
