The factor pairs of 1600 are (1600,1)(800,2)(400,4)(320,5)(200,8)(160,10)(100,16)(80,20)(64,25)(50,32) None of them add up to 332.

How about 2 and 12 or 4 and 10
To find two numbers that add up to -60 and multiply to 36, we can set up a system of equations. Let's call the two numbers x and y. The sum of the numbers is x + y = -60, and the product of the numbers is xy = 36. By solving these equations simultaneously, we find that the two numbers are -12 and -48.

There are really only three distinct factor pairs:(16, 1) (8, 2)(4, 4)I suppose if you count (1,16) and (2,8) as being different from (16, 1) and (8,2), you could end up with as many as five factor pairs.
The factor pairs of 1600 are (1600,1)(800,2)(400,4)(320,5)(200,8)(160,10)(100,16)(80,20)(64,25)(50,32)(40,40) None of them add up to 60.
The factor pairs of 3000 all have a product of 3000. None of them add up to -155.
The factor pairs of 1600 are (1600,1)(800,2)(400,4)(320,5)(200,8)(160,10)(100,16)(80,20)(64,25)(50,32) None of them add up to 332.
The factor pairs of 1600 are (1600,1)(800,2)(400,4)(320,5)(200,8)(160,10)(100,16)(80,20)(64,25)(50,32)(40,40) None of them add up to 60. If that was -1600, you could use 80 and -20.

When you say "factors" there are 3 different things this could mean.Prime factors (this is probably not the one you want, but it will help later). You usually do this with a "factor tree". Pencil and paper would make it look like a tree!Find the prime factorization of 60: 60 = 6x10 = (2x3)x(2x5) = 2x2x3x5. (=22x3x5).All factors of a number (this sounds like the one you want): All the numbers from 1 to 60 inclusive which divide evenly into the number; you can find these by looking at the prime factors: 1,2,3,4,5,6,10,12,15,20,30,60.All factor pairs: what two numbers can you multiply to give 60? They are made up from the factors you just found: 1x60, 2x30, 3x20; 4x15, 5x12, 6x10.
