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 10,238,131, 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 | 10,238,131 | |
| -1 | -10,238,131 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,238,131.
Example:
1 x 10,238,131 = 10,238,131
and
-1 x -10,238,131 = 10,238,131
Notice both answers equal 10,238,131
With that explanation out of the way, let's continue. Next, we take the number 10,238,131 and divide it by 2:
10,238,131 ÷ 2 = 5,119,065.5
If the quotient is a whole number, then 2 and 5,119,065.5 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 | 10,238,131 | |
| -1 | -10,238,131 |
Now, we try dividing 10,238,131 by 3:
10,238,131 ÷ 3 = 3,412,710.3333
If the quotient is a whole number, then 3 and 3,412,710.3333 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 | 10,238,131 | |
| -1 | -10,238,131 |
Let's try dividing by 4:
10,238,131 ÷ 4 = 2,559,532.75
If the quotient is a whole number, then 4 and 2,559,532.75 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 | 10,238,131 | |
| -1 | 10,238,131 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 29 | 323 | 493 | 551 | 1,093 | 9,367 | 18,581 | 20,767 | 31,697 | 353,039 | 538,849 | 602,243 | 10,238,131 |
| -1 | -17 | -19 | -29 | -323 | -493 | -551 | -1,093 | -9,367 | -18,581 | -20,767 | -31,697 | -353,039 | -538,849 | -602,243 | -10,238,131 |
