There is no such number since you cannot list every non-zero number!
A multiple
Itself because 1 times a number = the same number
Yes. Every non-zero number is divisible by itself.
1.0070 has 5 significant figures. This is because when you are looking at a number with a decimal number, you start from the left and find a non-zero number. When you find the non-zero number, every number after it is significant.
This can not be done. Every non-negative number on the number line is the square root of its square. You would have to mark every number from zero on.
Not necessarily. A number is also a multiple of itself.
No. Every non-zero whole number is a multiple of 1.
The two factors of every non-zero number are 1 and the number itself.
A multiple
1 times a number equals itself. The number is the first on the list of multiples.
I'm not sure what you want. You can have 5 and 2 and any non-zero whole number. You can have 10 and any two non-zero whole numbers. You can have any even number, then any multiple of 5, then any non-zero whole number. Or any multiple of ten, then any two non-zero whole numbers. I think I covered the possibilities.

Every number is divisible by any non-zero number. Whether or not it is evenly divisible depends on the value of Y.
You multiply the fraction by any non-zero multiple of its denominator.
Every other non-zero integer.
