A number is divided evenly by its factors, then what to call this number with?

For example:
10 is divided evenly by 1, 2 and 5.
1, 2, 5 are the factors

Then, how can I denote "10" with a noun?

(I tried searching math.stackexchange, but this seems to be too elementary there)

  • A number that can be factored is factorable.

The number 10 is a composite number according to the following definition:

composite number (kəm-pŏz′ĭt)

An integer that can be divided by at least one other integer besides itself and 1 without leaving a remainder. 24 is a composite number since it can be divided by 2, 3, 4, 6, 8, and 12. No prime numbers are composite numbers. Compare prime number.

A number that can be divided only by itself and 1 without leaving a remainder is a prime number.

10 is a multiple of 1, 2, 5, and 10. (Note that every number is a factor and mul,tiple of itself.)

In science, a multiple is the product of any quantity and an integer.[1][2][3] In other words, for the quantities a and b, we say that b is a multiple of a if b = na for some integer n, which is called the multiplier. If a is not zero, this is equivalent to saying that b/a is an integer.[4][5][6]

  • This answer agrees with the OED: 2.Multiple (n.) 2. a. Mathematics. A quantity which contains another quantity some number of times without remainder; a quantity which is the product of a given quantity and some other, esp. one which results from multiplying the given quantity by an integer. Thus 4 is a multiple of 2; 6 is a multiple of 2 and 3; 12 is the lowest common multiple of 2, 3, and 4.

10 is the product of 1, 2, and 5. Those are all integers. They are also whole numbers. Multiplied together, 1, 2, and 5 make 10. 2 and 5 are 10's prime factors.
