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 9,935,515, 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 | 9,935,515 | |
| -1 | -9,935,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,935,515.
Example:
1 x 9,935,515 = 9,935,515
and
-1 x -9,935,515 = 9,935,515
Notice both answers equal 9,935,515
With that explanation out of the way, let's continue. Next, we take the number 9,935,515 and divide it by 2:
9,935,515 ÷ 2 = 4,967,757.5
If the quotient is a whole number, then 2 and 4,967,757.5 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 | 9,935,515 | |
| -1 | -9,935,515 |
Now, we try dividing 9,935,515 by 3:
9,935,515 ÷ 3 = 3,311,838.3333
If the quotient is a whole number, then 3 and 3,311,838.3333 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 | 9,935,515 | |
| -1 | -9,935,515 |
Let's try dividing by 4:
9,935,515 ÷ 4 = 2,483,878.75
If the quotient is a whole number, then 4 and 2,483,878.75 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 | 9,935,515 | |
| -1 | 9,935,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 83 | 89 | 269 | 415 | 445 | 1,345 | 7,387 | 22,327 | 23,941 | 36,935 | 111,635 | 119,705 | 1,987,103 | 9,935,515 |
| -1 | -5 | -83 | -89 | -269 | -415 | -445 | -1,345 | -7,387 | -22,327 | -23,941 | -36,935 | -111,635 | -119,705 | -1,987,103 | -9,935,515 |
