 A:
Positive:   1 x 284697 x 406749 x 58183 x 343
Negative: -1 x -28469-7 x -4067-49 x -581-83 x -343


How do I find the factor combinations of the number 28,469?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 28,469, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 28,469
-1 -28,469

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,469.

Example:
1 x 28,469 = 28,469
and
-1 x -28,469 = 28,469
Notice both answers equal 28,469

With that explanation out of the way, let's continue. Next, we take the number 28,469 and divide it by 2:

28,469 ÷ 2 = 14,234.5

If the quotient is a whole number, then 2 and 14,234.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 28,469
-1 -28,469

Now, we try dividing 28,469 by 3:

28,469 ÷ 3 = 9,489.6667

If the quotient is a whole number, then 3 and 9,489.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 28,469
-1 -28,469

Let's try dividing by 4:

28,469 ÷ 4 = 7,117.25

If the quotient is a whole number, then 4 and 7,117.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 28,469
-1 28,469
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

1749833435814,06728,469
-1-7-49-83-343-581-4,067-28,469
