**multiple**

A multiple of a number is the product of that number and any other whole number. Zero is a multiple of every number.

**prime number**

A number whose only factors are itself and 1.

**composite number**

A natural number that is not prime.

Factoring is like taking a number apart. It means to express a number as the product of its factors. Factors are either composite number or prime numbers (except that 0 and 1 are neither prime nor composite).

The number 12 is a multiple of 3, because it can be divided evenly by 3.

**3 x 4 = 12**

**3 and 4 are both factors of 12**

12 is a multiple of both 3 and 4.

12 is a multiple of both 3 and 4.
