How do I find the factor combinations of the number 921,823?

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 921,823, 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.

1 921,823
-1 -921,823

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 921,823.

Example:
1 x 921,823 = 921,823
and
-1 x -921,823 = 921,823
Notice both answers equal 921,823

With that explanation out of the way, let's continue. Next, we take the number 921,823 and divide it by 2:

921,823 ÷ 2 = 460,911.5

If the quotient is a whole number, then 2 and 460,911.5 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:

1 921,823
-1 -921,823

Now, we try dividing 921,823 by 3:

921,823 ÷ 3 = 307,274.3333

If the quotient is a whole number, then 3 and 307,274.3333 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:

1 921,823
-1 -921,823

Let's try dividing by 4:

921,823 ÷ 4 = 230,455.75

If the quotient is a whole number, then 4 and 230,455.75 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:

1 921,823
-1 921,823
Keep dividing by the next highest number until you cannot divide anymore.

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

1719291332032395511,6733,8574,5416,93131,78748,517131,689921,823
