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 9,231,799, 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 | 9,231,799 | |
| -1 | -9,231,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,231,799.
Example:
1 x 9,231,799 = 9,231,799
and
-1 x -9,231,799 = 9,231,799
Notice both answers equal 9,231,799
With that explanation out of the way, let's continue. Next, we take the number 9,231,799 and divide it by 2:
9,231,799 ÷ 2 = 4,615,899.5
If the quotient is a whole number, then 2 and 4,615,899.5 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 | 9,231,799 | |
| -1 | -9,231,799 |
Now, we try dividing 9,231,799 by 3:
9,231,799 ÷ 3 = 3,077,266.3333
If the quotient is a whole number, then 3 and 3,077,266.3333 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 | 9,231,799 | |
| -1 | -9,231,799 |
Let's try dividing by 4:
9,231,799 ÷ 4 = 2,307,949.75
If the quotient is a whole number, then 4 and 2,307,949.75 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 | 9,231,799 | |
| -1 | 9,231,799 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 73 | 173 | 731 | 1,241 | 2,941 | 3,139 | 7,439 | 12,629 | 53,363 | 126,463 | 214,693 | 543,047 | 9,231,799 |
| -1 | -17 | -43 | -73 | -173 | -731 | -1,241 | -2,941 | -3,139 | -7,439 | -12,629 | -53,363 | -126,463 | -214,693 | -543,047 | -9,231,799 |
