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 9,111,361, 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 | 9,111,361 | |
| -1 | -9,111,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,111,361.
Example:
1 x 9,111,361 = 9,111,361
and
-1 x -9,111,361 = 9,111,361
Notice both answers equal 9,111,361
With that explanation out of the way, let's continue. Next, we take the number 9,111,361 and divide it by 2:
9,111,361 ÷ 2 = 4,555,680.5
If the quotient is a whole number, then 2 and 4,555,680.5 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 | 9,111,361 | |
| -1 | -9,111,361 |
Now, we try dividing 9,111,361 by 3:
9,111,361 ÷ 3 = 3,037,120.3333
If the quotient is a whole number, then 3 and 3,037,120.3333 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 | 9,111,361 | |
| -1 | -9,111,361 |
Let's try dividing by 4:
9,111,361 ÷ 4 = 2,277,840.25
If the quotient is a whole number, then 4 and 2,277,840.25 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 | 9,111,361 | |
| -1 | 9,111,361 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 127 | 259 | 277 | 889 | 1,939 | 4,699 | 10,249 | 32,893 | 35,179 | 71,743 | 246,253 | 1,301,623 | 9,111,361 |
| -1 | -7 | -37 | -127 | -259 | -277 | -889 | -1,939 | -4,699 | -10,249 | -32,893 | -35,179 | -71,743 | -246,253 | -1,301,623 | -9,111,361 |
