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 10,231,637, 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 | 10,231,637 | |
| -1 | -10,231,637 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,231,637.
Example:
1 x 10,231,637 = 10,231,637
and
-1 x -10,231,637 = 10,231,637
Notice both answers equal 10,231,637
With that explanation out of the way, let's continue. Next, we take the number 10,231,637 and divide it by 2:
10,231,637 ÷ 2 = 5,115,818.5
If the quotient is a whole number, then 2 and 5,115,818.5 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 | 10,231,637 | |
| -1 | -10,231,637 |
Now, we try dividing 10,231,637 by 3:
10,231,637 ÷ 3 = 3,410,545.6667
If the quotient is a whole number, then 3 and 3,410,545.6667 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 | 10,231,637 | |
| -1 | -10,231,637 |
Let's try dividing by 4:
10,231,637 ÷ 4 = 2,557,909.25
If the quotient is a whole number, then 4 and 2,557,909.25 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 | 10,231,637 | |
| -1 | 10,231,637 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 67 | 221 | 691 | 871 | 1,139 | 8,983 | 11,747 | 14,807 | 46,297 | 152,711 | 601,861 | 787,049 | 10,231,637 |
| -1 | -13 | -17 | -67 | -221 | -691 | -871 | -1,139 | -8,983 | -11,747 | -14,807 | -46,297 | -152,711 | -601,861 | -787,049 | -10,231,637 |
