First we have to find the factors of 144. 144 = 2 2 2 2 3 3. Then we will find the pairs of numbers which product is 144. 1 144 = 144, 2 72 = 144, 3 48 = 144, 4 36 = 144, 6 24 = 144, 8 18 = 144, 9 16 = 144. And because of the commutative property of multiplication: 16 9 = 144, 18 8 = 144, 24 6 = 144, 36 4 = 144, 48 3 = 144, 48 3 = 144, 72 2 = 144 and 144 1 = 144.
