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 5,786,123, 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 | 5,786,123 | |
| -1 | -5,786,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,786,123.
Example:
1 x 5,786,123 = 5,786,123
and
-1 x -5,786,123 = 5,786,123
Notice both answers equal 5,786,123
With that explanation out of the way, let's continue. Next, we take the number 5,786,123 and divide it by 2:
5,786,123 ÷ 2 = 2,893,061.5
If the quotient is a whole number, then 2 and 2,893,061.5 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 | 5,786,123 | |
| -1 | -5,786,123 |
Now, we try dividing 5,786,123 by 3:
5,786,123 ÷ 3 = 1,928,707.6667
If the quotient is a whole number, then 3 and 1,928,707.6667 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 | 5,786,123 | |
| -1 | -5,786,123 |
Let's try dividing by 4:
5,786,123 ÷ 4 = 1,446,530.75
If the quotient is a whole number, then 4 and 1,446,530.75 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 | 5,786,123 | |
| -1 | 5,786,123 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 47 | 301 | 329 | 409 | 2,021 | 2,863 | 14,147 | 17,587 | 19,223 | 123,109 | 134,561 | 826,589 | 5,786,123 |
| -1 | -7 | -43 | -47 | -301 | -329 | -409 | -2,021 | -2,863 | -14,147 | -17,587 | -19,223 | -123,109 | -134,561 | -826,589 | -5,786,123 |
