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 9,074,681, 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 | 9,074,681 | |
| -1 | -9,074,681 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,074,681.
Example:
1 x 9,074,681 = 9,074,681
and
-1 x -9,074,681 = 9,074,681
Notice both answers equal 9,074,681
With that explanation out of the way, let's continue. Next, we take the number 9,074,681 and divide it by 2:
9,074,681 ÷ 2 = 4,537,340.5
If the quotient is a whole number, then 2 and 4,537,340.5 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 | 9,074,681 | |
| -1 | -9,074,681 |
Now, we try dividing 9,074,681 by 3:
9,074,681 ÷ 3 = 3,024,893.6667
If the quotient is a whole number, then 3 and 3,024,893.6667 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 | 9,074,681 | |
| -1 | -9,074,681 |
Let's try dividing by 4:
9,074,681 ÷ 4 = 2,268,670.25
If the quotient is a whole number, then 4 and 2,268,670.25 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 | 9,074,681 | |
| -1 | 9,074,681 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 67 | 77 | 469 | 737 | 1,759 | 5,159 | 12,313 | 19,349 | 117,853 | 135,443 | 824,971 | 1,296,383 | 9,074,681 |
| -1 | -7 | -11 | -67 | -77 | -469 | -737 | -1,759 | -5,159 | -12,313 | -19,349 | -117,853 | -135,443 | -824,971 | -1,296,383 | -9,074,681 |
