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 9,707,765, 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 | 9,707,765 | |
| -1 | -9,707,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,707,765.
Example:
1 x 9,707,765 = 9,707,765
and
-1 x -9,707,765 = 9,707,765
Notice both answers equal 9,707,765
With that explanation out of the way, let's continue. Next, we take the number 9,707,765 and divide it by 2:
9,707,765 ÷ 2 = 4,853,882.5
If the quotient is a whole number, then 2 and 4,853,882.5 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 | 9,707,765 | |
| -1 | -9,707,765 |
Now, we try dividing 9,707,765 by 3:
9,707,765 ÷ 3 = 3,235,921.6667
If the quotient is a whole number, then 3 and 3,235,921.6667 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 | 9,707,765 | |
| -1 | -9,707,765 |
Let's try dividing by 4:
9,707,765 ÷ 4 = 2,426,941.25
If the quotient is a whole number, then 4 and 2,426,941.25 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 | 9,707,765 | |
| -1 | 9,707,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 19 | 85 | 95 | 323 | 1,615 | 6,011 | 30,055 | 102,187 | 114,209 | 510,935 | 571,045 | 1,941,553 | 9,707,765 |
| -1 | -5 | -17 | -19 | -85 | -95 | -323 | -1,615 | -6,011 | -30,055 | -102,187 | -114,209 | -510,935 | -571,045 | -1,941,553 | -9,707,765 |
