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 10,313,135, 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 | 10,313,135 | |
| -1 | -10,313,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,313,135.
Example:
1 x 10,313,135 = 10,313,135
and
-1 x -10,313,135 = 10,313,135
Notice both answers equal 10,313,135
With that explanation out of the way, let's continue. Next, we take the number 10,313,135 and divide it by 2:
10,313,135 ÷ 2 = 5,156,567.5
If the quotient is a whole number, then 2 and 5,156,567.5 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 | 10,313,135 | |
| -1 | -10,313,135 |
Now, we try dividing 10,313,135 by 3:
10,313,135 ÷ 3 = 3,437,711.6667
If the quotient is a whole number, then 3 and 3,437,711.6667 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 | 10,313,135 | |
| -1 | -10,313,135 |
Let's try dividing by 4:
10,313,135 ÷ 4 = 2,578,283.75
If the quotient is a whole number, then 4 and 2,578,283.75 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 | 10,313,135 | |
| -1 | 10,313,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 17,333 | 86,665 | 121,331 | 294,661 | 606,655 | 1,473,305 | 2,062,627 | 10,313,135 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -17,333 | -86,665 | -121,331 | -294,661 | -606,655 | -1,473,305 | -2,062,627 | -10,313,135 |
