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 868,231, it is easier to work with a table - it's called factoring from the outside in.
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 | 868,231 | |
| -1 | -868,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 868,231.
Example:
1 x 868,231 = 868,231
and
-1 x -868,231 = 868,231
Notice both answers equal 868,231
With that explanation out of the way, let's continue. Next, we take the number 868,231 and divide it by 2:
868,231 ÷ 2 = 434,115.5
If the quotient is a whole number, then 2 and 434,115.5 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 | 868,231 | |
| -1 | -868,231 |
Now, we try dividing 868,231 by 3:
868,231 ÷ 3 = 289,410.3333
If the quotient is a whole number, then 3 and 289,410.3333 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 | 868,231 | |
| -1 | -868,231 |
Let's try dividing by 4:
868,231 ÷ 4 = 217,057.75
If the quotient is a whole number, then 4 and 217,057.75 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 | 868,231 | |
| -1 | 868,231 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 47 | 49 | 91 | 203 | 329 | 377 | 611 | 637 | 1,363 | 1,421 | 2,303 | 2,639 | 4,277 | 9,541 | 17,719 | 18,473 | 29,939 | 66,787 | 124,033 | 868,231 |
| -1 | -7 | -13 | -29 | -47 | -49 | -91 | -203 | -329 | -377 | -611 | -637 | -1,363 | -1,421 | -2,303 | -2,639 | -4,277 | -9,541 | -17,719 | -18,473 | -29,939 | -66,787 | -124,033 | -868,231 |
