Exercise 6 Page 85

A factor pair of a number is two integers that result in the given number when multiplied together. Let's write 72 as the product of two numbers in as many ways as possible. 1* 72 =& 72 2 * 36=& 72 3* 24 =& 72 4* 18 =& 72 6* 12 =& 72 8* 9 =& 72 We found that 72 has six factor pairs. (1,72),(2,36),(3,24),(4,18),(6,12),(8,9)
