Every number is both a factor and a multiple of itself. Every other factor is smaller than the number, every other multiple is larger than the number.
It has to be a whole number, or else every number would be a multiple of every other number.
Every whole number (obviously not 0) is a multiple of 1.
One is a factor of every number. One is only a multiple of itself.
Every other number that ends in 5 is a multiple of 5 this is why

No. * * * * * Yes. In fact, zero is a multiple of every number.
Not in the normal usage of the words. Usually, a number is considered to be a multiple of another number only of there is an integer you can multiply the other number by in order to get the first number. If you allowed multiplication by non-integers, then every number would be a multiple of every other number except zero and the term "multiple" would be fairly useless. So in the normal way of speaking, 39 is not a multiple of 6 because there is no integer (whole number) you can multiply 6 by in order to get 39.
If one number is a multiple of the other, the number that is the multiple is the LCM.
Yes. And that multiple is 1.
