How do I find the factor combinations of the number 867,295?

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 867,295, 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.

1 867,295
-1 -867,295

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 867,295.

Example:
1 x 867,295 = 867,295
and
-1 x -867,295 = 867,295
Notice both answers equal 867,295

With that explanation out of the way, let's continue. Next, we take the number 867,295 and divide it by 2:

867,295 ÷ 2 = 433,647.5

If the quotient is a whole number, then 2 and 433,647.5 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:

1 867,295
-1 -867,295

Now, we try dividing 867,295 by 3:

867,295 ÷ 3 = 289,098.3333

If the quotient is a whole number, then 3 and 289,098.3333 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:

1 867,295
-1 -867,295

Let's try dividing by 4:

867,295 ÷ 4 = 216,823.75

If the quotient is a whole number, then 4 and 216,823.75 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:

1 867,295
-1 867,295
Keep dividing by the next highest number until you cannot divide anymore.

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

15111355651437151,2136,06513,34315,76966,71578,845173,459867,295
