 A:
Positive:   1 x 278537 x 397923 x 1211161 x 173
Negative: -1 x -27853-7 x -3979-23 x -1211-161 x -173


How do I find the factor combinations of the number 27,853?

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 27,853, 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 27,853
-1 -27,853

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 27,853.

Example:
1 x 27,853 = 27,853
and
-1 x -27,853 = 27,853
Notice both answers equal 27,853

With that explanation out of the way, let's continue. Next, we take the number 27,853 and divide it by 2:

27,853 ÷ 2 = 13,926.5

If the quotient is a whole number, then 2 and 13,926.5 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 27,853
-1 -27,853

Now, we try dividing 27,853 by 3:

27,853 ÷ 3 = 9,284.3333

If the quotient is a whole number, then 3 and 9,284.3333 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 27,853
-1 -27,853

Let's try dividing by 4:

27,853 ÷ 4 = 6,963.25

If the quotient is a whole number, then 4 and 6,963.25 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 27,853
-1 27,853
Keep dividing by the next highest number until you cannot divide anymore.

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

17231611731,2113,97927,853
-1-7-23-161-173-1,211-3,979-27,853
