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 9,074,723, 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 | 9,074,723 | |
| -1 | -9,074,723 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,074,723.
Example:
1 x 9,074,723 = 9,074,723
and
-1 x -9,074,723 = 9,074,723
Notice both answers equal 9,074,723
With that explanation out of the way, let's continue. Next, we take the number 9,074,723 and divide it by 2:
9,074,723 ÷ 2 = 4,537,361.5
If the quotient is a whole number, then 2 and 4,537,361.5 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 | 9,074,723 | |
| -1 | -9,074,723 |
Now, we try dividing 9,074,723 by 3:
9,074,723 ÷ 3 = 3,024,907.6667
If the quotient is a whole number, then 3 and 3,024,907.6667 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 | 9,074,723 | |
| -1 | -9,074,723 |
Let's try dividing by 4:
9,074,723 ÷ 4 = 2,268,680.75
If the quotient is a whole number, then 4 and 2,268,680.75 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 | 9,074,723 | |
| -1 | 9,074,723 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 31 | 71 | 133 | 217 | 497 | 589 | 961 | 1,349 | 2,201 | 4,123 | 6,727 | 9,443 | 15,407 | 18,259 | 41,819 | 68,231 | 127,813 | 292,733 | 477,617 | 1,296,389 | 9,074,723 |
| -1 | -7 | -19 | -31 | -71 | -133 | -217 | -497 | -589 | -961 | -1,349 | -2,201 | -4,123 | -6,727 | -9,443 | -15,407 | -18,259 | -41,819 | -68,231 | -127,813 | -292,733 | -477,617 | -1,296,389 | -9,074,723 |
