1 is a multiple of every integer?

So, in either system, 1 is a multiple of every number, but the same is true of every other number. On the contrary, while both the naturals and the integers are closed under multiplication, i.e. the product of two integers is always an integer and the same for the naturals, neither is closed under division.

In other words, any integer a can be written as a = a/1, which is a rational number. Thus, every integer is a rational number. Clearly, 3/2,-5/3, etc. are rational numbers but they are not integers.

36, 38, 40……etc. are the multiples of 2 or 2 is one of the factors of these numbers. So, all these numbers are called even numbers. Thus, any number divisible by 2 is an even number.

There is only one number whose multiple is 0. And that number is 0. If you take any number other than 0, it's multiple is non-zero. As examples: 2 is a multiple of 1, 4 is twice the two, 6 is three times 2, 16 is 4 times 4, 35 is 7 times 5 and so on.

The Inclusion-Exclusion principle. How many integers from 1 to 50 are multiples of 2 or 3 but not both? From 1 to 100, there are 50/2=25 numbers which are multiples of 2. There are 50/3=16 numbers which are multiples of 3.

The set of multiples of a number is therefore an infinite set. ... The statement "48 is a multiple of 12" is equivalent to "48 is divisible by 12" or to "12 is a divisor of 48". The multiples of 2 are the so-called even numbers 2, 4, 6, 8, 10, 12, ... .

Multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40 and so on. Since 80 is on the list of multiples of 4, the answer to the question "Is 80 a multiple of 4?" is: Yes. ... If the result is a positive integer, then 80 is a multiple of 4. 80 divided by 4 equals 20, which is a positive integer.

Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and so on. Since 20 is on the list of multiples of 5, the answer to the question "Is 20 a multiple of 5?" is: Yes. ... If the result is a positive integer, then 20 is a multiple of 5. 20 divided by 5 equals 4, which is a positive integer.

Zero is a multiple of every number, though, again, a multiple that's not terribly informative. In particular, 0 is an even number, because it is a multiple of 2. ... The number 12 is a "multiple of 4" or a "multiple of 6" but not just "a multiple." (It is not, for example, "a multiple" of 5.)

For 23, the answer is: yes, 23 is a prime number because it has only two distinct divisors: 1 and itself (23). As a consequence, 23 is only a multiple of 1 and 23.
