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 10,313,645, 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 | 10,313,645 | |
| -1 | -10,313,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,313,645.
Example:
1 x 10,313,645 = 10,313,645
and
-1 x -10,313,645 = 10,313,645
Notice both answers equal 10,313,645
With that explanation out of the way, let's continue. Next, we take the number 10,313,645 and divide it by 2:
10,313,645 ÷ 2 = 5,156,822.5
If the quotient is a whole number, then 2 and 5,156,822.5 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 | 10,313,645 | |
| -1 | -10,313,645 |
Now, we try dividing 10,313,645 by 3:
10,313,645 ÷ 3 = 3,437,881.6667
If the quotient is a whole number, then 3 and 3,437,881.6667 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 | 10,313,645 | |
| -1 | -10,313,645 |
Let's try dividing by 4:
10,313,645 ÷ 4 = 2,578,411.25
If the quotient is a whole number, then 4 and 2,578,411.25 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 | 10,313,645 | |
| -1 | 10,313,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 67 | 85 | 335 | 1,139 | 1,811 | 5,695 | 9,055 | 30,787 | 121,337 | 153,935 | 606,685 | 2,062,729 | 10,313,645 |
| -1 | -5 | -17 | -67 | -85 | -335 | -1,139 | -1,811 | -5,695 | -9,055 | -30,787 | -121,337 | -153,935 | -606,685 | -2,062,729 | -10,313,645 |
