How do I find the factor combinations of the number 861,852?

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 861,852, 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.

1 861,852
-1 -861,852

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 861,852.

Example:
1 x 861,852 = 861,852
and
-1 x -861,852 = 861,852
Notice both answers equal 861,852

With that explanation out of the way, let's continue. Next, we take the number 861,852 and divide it by 2:

861,852 ÷ 2 = 430,926

If the quotient is a whole number, then 2 and 430,926 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 430,926 861,852
-1 -2 -430,926 -861,852

Now, we try dividing 861,852 by 3:

861,852 ÷ 3 = 287,284

If the quotient is a whole number, then 3 and 287,284 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 3 287,284 430,926 861,852
-1 -2 -3 -287,284 -430,926 -861,852

Let's try dividing by 4:

861,852 ÷ 4 = 215,463

If the quotient is a whole number, then 4 and 215,463 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

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

1 2 3 4 215,463 287,284 430,926 861,852
-1 -2 -3 -4 -215,463 -287,284 -430,926 861,852
Keep dividing by the next highest number until you cannot divide anymore.

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

123461271,821143,642215,463287,284430,926861,852
-1-2-3-4-6-12-71,821-143,642-215,463-287,284-430,926-861,852
