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 10,724,857, 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 | 10,724,857 | |
| -1 | -10,724,857 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,724,857.
Example:
1 x 10,724,857 = 10,724,857
and
-1 x -10,724,857 = 10,724,857
Notice both answers equal 10,724,857
With that explanation out of the way, let's continue. Next, we take the number 10,724,857 and divide it by 2:
10,724,857 ÷ 2 = 5,362,428.5
If the quotient is a whole number, then 2 and 5,362,428.5 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 | 10,724,857 | |
| -1 | -10,724,857 |
Now, we try dividing 10,724,857 by 3:
10,724,857 ÷ 3 = 3,574,952.3333
If the quotient is a whole number, then 3 and 3,574,952.3333 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 | 10,724,857 | |
| -1 | -10,724,857 |
Let's try dividing by 4:
10,724,857 ÷ 4 = 2,681,214.25
If the quotient is a whole number, then 4 and 2,681,214.25 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 | 10,724,857 | |
| -1 | 10,724,857 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 37 | 143 | 407 | 481 | 2,027 | 5,291 | 22,297 | 26,351 | 74,999 | 289,861 | 824,989 | 974,987 | 10,724,857 |
| -1 | -11 | -13 | -37 | -143 | -407 | -481 | -2,027 | -5,291 | -22,297 | -26,351 | -74,999 | -289,861 | -824,989 | -974,987 | -10,724,857 |
