How do I find the factor combinations of the number 826,181?

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 826,181, 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.

1 826,181
-1 -826,181

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 826,181.

Example:
1 x 826,181 = 826,181
and
-1 x -826,181 = 826,181
Notice both answers equal 826,181

With that explanation out of the way, let's continue. Next, we take the number 826,181 and divide it by 2:

826,181 ÷ 2 = 413,090.5

If the quotient is a whole number, then 2 and 413,090.5 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:

1 826,181
-1 -826,181

Now, we try dividing 826,181 by 3:

826,181 ÷ 3 = 275,393.6667

If the quotient is a whole number, then 3 and 275,393.6667 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:

1 826,181
-1 -826,181

Let's try dividing by 4:

826,181 ÷ 4 = 206,545.25

If the quotient is a whole number, then 4 and 206,545.25 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:

1 826,181
-1 826,181
Keep dividing by the next highest number until you cannot divide anymore.

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

1293189991926,65128,489826,181
-1-29-31-899-919-26,651-28,489-826,181
