How do I find the factor combinations of the number 802,711?

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 802,711, 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.

1 802,711
-1 -802,711

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 802,711.

Example:
1 x 802,711 = 802,711
and
-1 x -802,711 = 802,711
Notice both answers equal 802,711

With that explanation out of the way, let's continue. Next, we take the number 802,711 and divide it by 2:

802,711 ÷ 2 = 401,355.5

If the quotient is a whole number, then 2 and 401,355.5 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:

1 802,711
-1 -802,711

Now, we try dividing 802,711 by 3:

802,711 ÷ 3 = 267,570.3333

If the quotient is a whole number, then 3 and 267,570.3333 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:

1 802,711
-1 -802,711

Let's try dividing by 4:

802,711 ÷ 4 = 200,677.75

If the quotient is a whole number, then 4 and 200,677.75 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:

1 802,711
-1 802,711
Keep dividing by the next highest number until you cannot divide anymore.

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

1713918,82161,747114,673802,711
-1-7-13-91-8,821-61,747-114,673-802,711
