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 928,109, 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 | 928,109 | |
| -1 | -928,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 928,109.
Example:
1 x 928,109 = 928,109
and
-1 x -928,109 = 928,109
Notice both answers equal 928,109
With that explanation out of the way, let's continue. Next, we take the number 928,109 and divide it by 2:
928,109 ÷ 2 = 464,054.5
If the quotient is a whole number, then 2 and 464,054.5 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 | 928,109 | |
| -1 | -928,109 |
Now, we try dividing 928,109 by 3:
928,109 ÷ 3 = 309,369.6667
If the quotient is a whole number, then 3 and 309,369.6667 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 | 928,109 | |
| -1 | -928,109 |
Let's try dividing by 4:
928,109 ÷ 4 = 232,027.25
If the quotient is a whole number, then 4 and 232,027.25 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 | 928,109 | |
| -1 | 928,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 47 | 49 | 91 | 217 | 329 | 403 | 611 | 637 | 1,457 | 1,519 | 2,303 | 2,821 | 4,277 | 10,199 | 18,941 | 19,747 | 29,939 | 71,393 | 132,587 | 928,109 |
| -1 | -7 | -13 | -31 | -47 | -49 | -91 | -217 | -329 | -403 | -611 | -637 | -1,457 | -1,519 | -2,303 | -2,821 | -4,277 | -10,199 | -18,941 | -19,747 | -29,939 | -71,393 | -132,587 | -928,109 |
