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 9,110,861, 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 | 9,110,861 | |
| -1 | -9,110,861 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,110,861.
Example:
1 x 9,110,861 = 9,110,861
and
-1 x -9,110,861 = 9,110,861
Notice both answers equal 9,110,861
With that explanation out of the way, let's continue. Next, we take the number 9,110,861 and divide it by 2:
9,110,861 ÷ 2 = 4,555,430.5
If the quotient is a whole number, then 2 and 4,555,430.5 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 | 9,110,861 | |
| -1 | -9,110,861 |
Now, we try dividing 9,110,861 by 3:
9,110,861 ÷ 3 = 3,036,953.6667
If the quotient is a whole number, then 3 and 3,036,953.6667 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 | 9,110,861 | |
| -1 | -9,110,861 |
Let's try dividing by 4:
9,110,861 ÷ 4 = 2,277,715.25
If the quotient is a whole number, then 4 and 2,277,715.25 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 | 9,110,861 | |
| -1 | 9,110,861 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 67 | 323 | 421 | 1,139 | 1,273 | 7,157 | 7,999 | 21,641 | 28,207 | 135,983 | 479,519 | 535,933 | 9,110,861 |
| -1 | -17 | -19 | -67 | -323 | -421 | -1,139 | -1,273 | -7,157 | -7,999 | -21,641 | -28,207 | -135,983 | -479,519 | -535,933 | -9,110,861 |
