1, 2, 5, 10
A factor of 20 is a number that divides evenly into 20 without leaving a remainder. The factors of 20 are 1, 2, 4, 5, 10, and 20. Among these, the number 5 is a factor of 20 but not a multiple of 4 because it does not result from multiplying 4 by any integer.
Oh, what a happy little question! The number you're looking for is 5. You see, 5 is a factor of 20 because it can be divided evenly into 20, and it's also a multiple of 5 because, well, it is 5! Just remember, there are no mistakes, just happy little numbers.
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!
1 and 2
2 is the only number is that both a factor of 2 and a multiple of 2.
A multiple is found by multiplying the number. Whereas a factor is what the number can be divided by. For example - multiples of 10 are; 10, 20, 30, 40, ... Factors of 10 are; 1, 2, 5, 10
1, 2, 5, 10
A factor (or divisor) is a number which evenly goes into the number of which it is a factor. E.g. 5, 2, 10 and 4 are factors of 20. A multiple is a number which is a whole number of times larger than the number of which it is a multiple. E.g. 4, 6, 8, 10 and so on are multiples of 2. A product is very similar to a multiple; the product of two numbers is the two multiplied together. E.g. the product of 5 and 4 is twenty, as is the product of 10 and 2.

A factor of 20 is a number that divides evenly into 20 without leaving a remainder. The factors of 20 are 1, 2, 4, 5, 10, and 20. Among these, the number 5 is a factor of 20 but not a multiple of 4 because it does not result from multiplying 4 by any integer.
A factor of 2 is a whole number that divides (or goes into) 2, without remainder. 2 is a prime, so there is no factor of 2 other than 1 and 2 itself. A multiple of 2 is any number that 2 goes into, such as 2, 4, 6, 20002 etc. The number that is both a factor and multiple of 2 is 2.

Since 10 is a factor of 20, all multiples of 20 are multiples of 10. This is also true of 1, 2, 4 and 5.
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.
It must be 10.
