To find two numbers that multiply to 156 and add up to -13, we can set up a system of equations. Let's call the two numbers x and y. We have the following equations: xy = 156 and x + y = -13. By factoring 156 into its prime factors (2 x 2 x 3 x 13), we can see that the two numbers are -12 and -13. Therefore, -12 x -13 = 156 and -12 + (-13) = -13.
The first five multiples of 12 are: 12, 24, 36, 48, 60
