The only prime factor of 4 is 2. No prime number is a multiple of 5.
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.
3.
Any multiple of 30.
Oh, dude, that's like asking me to find a needle in a haystack... if the haystack was made of numbers. So, a number that's a factor of 30 means it divides evenly into 30, right? And being a multiple of 2 just means it's, like, even. So, the number you're looking for is 2 because it's, like, the cool kid that fits both criteria.

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!
A factor is what goes into a number, a multiple is what a number goes into. 3 is a factor of 9 27 is a multiple of 9.
None of them.
