How do I find the factor combinations of the number 863,071?

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 863,071, 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.

1 863,071
-1 -863,071

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 863,071.

Example:
1 x 863,071 = 863,071
and
-1 x -863,071 = 863,071
Notice both answers equal 863,071

With that explanation out of the way, let's continue. Next, we take the number 863,071 and divide it by 2:

863,071 ÷ 2 = 431,535.5

If the quotient is a whole number, then 2 and 431,535.5 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:

1 863,071
-1 -863,071

Now, we try dividing 863,071 by 3:

863,071 ÷ 3 = 287,690.3333

If the quotient is a whole number, then 3 and 287,690.3333 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:

1 863,071
-1 -863,071

Let's try dividing by 4:

863,071 ÷ 4 = 215,767.75

If the quotient is a whole number, then 4 and 215,767.75 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:

1 863,071
-1 863,071
Keep dividing by the next highest number until you cannot divide anymore.

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

111313412,53127,84178,461863,071
-1-11-31-341-2,531-27,841-78,461-863,071
