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 31,524,233, 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 | 31,524,233 | |
| -1 | -31,524,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,524,233.
Example:
1 x 31,524,233 = 31,524,233
and
-1 x -31,524,233 = 31,524,233
Notice both answers equal 31,524,233
With that explanation out of the way, let's continue. Next, we take the number 31,524,233 and divide it by 2:
31,524,233 ÷ 2 = 15,762,116.5
If the quotient is a whole number, then 2 and 15,762,116.5 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 | 31,524,233 | |
| -1 | -31,524,233 |
Now, we try dividing 31,524,233 by 3:
31,524,233 ÷ 3 = 10,508,077.6667
If the quotient is a whole number, then 3 and 10,508,077.6667 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 | 31,524,233 | |
| -1 | -31,524,233 |
Let's try dividing by 4:
31,524,233 ÷ 4 = 7,881,058.25
If the quotient is a whole number, then 4 and 7,881,058.25 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 | 31,524,233 | |
| -1 | 31,524,233 |
If you did it right, you will end up with this table:
| 1 | 13 | 107 | 131 | 173 | 1,391 | 1,703 | 2,249 | 14,017 | 18,511 | 22,663 | 182,221 | 240,643 | 294,619 | 2,424,941 | 31,524,233 |
| -1 | -13 | -107 | -131 | -173 | -1,391 | -1,703 | -2,249 | -14,017 | -18,511 | -22,663 | -182,221 | -240,643 | -294,619 | -2,424,941 | -31,524,233 |
