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 10,813,705, 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 | 10,813,705 | |
| -1 | -10,813,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,813,705.
Example:
1 x 10,813,705 = 10,813,705
and
-1 x -10,813,705 = 10,813,705
Notice both answers equal 10,813,705
With that explanation out of the way, let's continue. Next, we take the number 10,813,705 and divide it by 2:
10,813,705 ÷ 2 = 5,406,852.5
If the quotient is a whole number, then 2 and 5,406,852.5 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 | 10,813,705 | |
| -1 | -10,813,705 |
Now, we try dividing 10,813,705 by 3:
10,813,705 ÷ 3 = 3,604,568.3333
If the quotient is a whole number, then 3 and 3,604,568.3333 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 | 10,813,705 | |
| -1 | -10,813,705 |
Let's try dividing by 4:
10,813,705 ÷ 4 = 2,703,426.25
If the quotient is a whole number, then 4 and 2,703,426.25 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 | 10,813,705 | |
| -1 | 10,813,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 509 | 607 | 2,545 | 3,035 | 3,563 | 4,249 | 17,815 | 21,245 | 308,963 | 1,544,815 | 2,162,741 | 10,813,705 |
| -1 | -5 | -7 | -35 | -509 | -607 | -2,545 | -3,035 | -3,563 | -4,249 | -17,815 | -21,245 | -308,963 | -1,544,815 | -2,162,741 | -10,813,705 |
