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 9,112,799, 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 | 9,112,799 | |
| -1 | -9,112,799 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,112,799.
Example:
1 x 9,112,799 = 9,112,799
and
-1 x -9,112,799 = 9,112,799
Notice both answers equal 9,112,799
With that explanation out of the way, let's continue. Next, we take the number 9,112,799 and divide it by 2:
9,112,799 ÷ 2 = 4,556,399.5
If the quotient is a whole number, then 2 and 4,556,399.5 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 | 9,112,799 | |
| -1 | -9,112,799 |
Now, we try dividing 9,112,799 by 3:
9,112,799 ÷ 3 = 3,037,599.6667
If the quotient is a whole number, then 3 and 3,037,599.6667 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 | 9,112,799 | |
| -1 | -9,112,799 |
Let's try dividing by 4:
9,112,799 ÷ 4 = 2,278,199.75
If the quotient is a whole number, then 4 and 2,278,199.75 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 | 9,112,799 | |
| -1 | 9,112,799 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 89 | 317 | 323 | 1,513 | 1,691 | 5,389 | 6,023 | 28,213 | 28,747 | 102,391 | 479,621 | 536,047 | 9,112,799 |
| -1 | -17 | -19 | -89 | -317 | -323 | -1,513 | -1,691 | -5,389 | -6,023 | -28,213 | -28,747 | -102,391 | -479,621 | -536,047 | -9,112,799 |
