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 8,961,845, 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 | 8,961,845 | |
| -1 | -8,961,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,961,845.
Example:
1 x 8,961,845 = 8,961,845
and
-1 x -8,961,845 = 8,961,845
Notice both answers equal 8,961,845
With that explanation out of the way, let's continue. Next, we take the number 8,961,845 and divide it by 2:
8,961,845 ÷ 2 = 4,480,922.5
If the quotient is a whole number, then 2 and 4,480,922.5 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 | 8,961,845 | |
| -1 | -8,961,845 |
Now, we try dividing 8,961,845 by 3:
8,961,845 ÷ 3 = 2,987,281.6667
If the quotient is a whole number, then 3 and 2,987,281.6667 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 | 8,961,845 | |
| -1 | -8,961,845 |
Let's try dividing by 4:
8,961,845 ÷ 4 = 2,240,461.25
If the quotient is a whole number, then 4 and 2,240,461.25 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 | 8,961,845 | |
| -1 | 8,961,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 73 | 215 | 365 | 571 | 2,855 | 3,139 | 15,695 | 24,553 | 41,683 | 122,765 | 208,415 | 1,792,369 | 8,961,845 |
| -1 | -5 | -43 | -73 | -215 | -365 | -571 | -2,855 | -3,139 | -15,695 | -24,553 | -41,683 | -122,765 | -208,415 | -1,792,369 | -8,961,845 |
