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 9,210,685, 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 | 9,210,685 | |
| -1 | -9,210,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,210,685.
Example:
1 x 9,210,685 = 9,210,685
and
-1 x -9,210,685 = 9,210,685
Notice both answers equal 9,210,685
With that explanation out of the way, let's continue. Next, we take the number 9,210,685 and divide it by 2:
9,210,685 ÷ 2 = 4,605,342.5
If the quotient is a whole number, then 2 and 4,605,342.5 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 | 9,210,685 | |
| -1 | -9,210,685 |
Now, we try dividing 9,210,685 by 3:
9,210,685 ÷ 3 = 3,070,228.3333
If the quotient is a whole number, then 3 and 3,070,228.3333 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 | 9,210,685 | |
| -1 | -9,210,685 |
Let's try dividing by 4:
9,210,685 ÷ 4 = 2,302,671.25
If the quotient is a whole number, then 4 and 2,302,671.25 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 | 9,210,685 | |
| -1 | 9,210,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 9,851 | 49,255 | 108,361 | 167,467 | 541,805 | 837,335 | 1,842,137 | 9,210,685 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -9,851 | -49,255 | -108,361 | -167,467 | -541,805 | -837,335 | -1,842,137 | -9,210,685 |
