The rules of divisibility tell you that 40 is divisible by 1, 2, 4 and 5. Dividing 40 by those numbers gives you 40, 20, 10 and 8. Writing them together gives you the factor pairs of 40.

(40,1)(20,2)(10,4)(8,5)

There are infinitely many pairs. The simplest to find is 1 and 40.

The factor pairs of 40 are (40,1)(20,2)(10,4)(8,5) None of them total 3. If that was -40, you could use 8 and -5

A product is the result of two numbers being multiplied together. 5 * 8 = 40 The product in the above example is 40. A factor pair are two numbers that when multiplied together equal the given product. In the above example, 5 and 8 are a factor pair of 40, because 5 times 8 equals 40. Other factor pairs of 40 are: 1 * 40 = 40 2 * 20 = 40 4 * 10 = 40 5 * 8 = 40 1 * 32 = 32 2 * 16 = 32 4 * 8 = 32 A great calculator for finding the factor pairs of a product can be found here: http://www2.whidbey.net/ohmsmath/webwork/javascript/fctrpr.htm
