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 9,250,085, 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 | 9,250,085 | |
| -1 | -9,250,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,250,085.
Example:
1 x 9,250,085 = 9,250,085
and
-1 x -9,250,085 = 9,250,085
Notice both answers equal 9,250,085
With that explanation out of the way, let's continue. Next, we take the number 9,250,085 and divide it by 2:
9,250,085 ÷ 2 = 4,625,042.5
If the quotient is a whole number, then 2 and 4,625,042.5 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 | 9,250,085 | |
| -1 | -9,250,085 |
Now, we try dividing 9,250,085 by 3:
9,250,085 ÷ 3 = 3,083,361.6667
If the quotient is a whole number, then 3 and 3,083,361.6667 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 | 9,250,085 | |
| -1 | -9,250,085 |
Let's try dividing by 4:
9,250,085 ÷ 4 = 2,312,521.25
If the quotient is a whole number, then 4 and 2,312,521.25 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 | 9,250,085 | |
| -1 | 9,250,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 101 | 505 | 1,313 | 1,409 | 6,565 | 7,045 | 18,317 | 91,585 | 142,309 | 711,545 | 1,850,017 | 9,250,085 |
| -1 | -5 | -13 | -65 | -101 | -505 | -1,313 | -1,409 | -6,565 | -7,045 | -18,317 | -91,585 | -142,309 | -711,545 | -1,850,017 | -9,250,085 |
