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 12,593,791, 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 | 12,593,791 | |
| -1 | -12,593,791 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,593,791.
Example:
1 x 12,593,791 = 12,593,791
and
-1 x -12,593,791 = 12,593,791
Notice both answers equal 12,593,791
With that explanation out of the way, let's continue. Next, we take the number 12,593,791 and divide it by 2:
12,593,791 ÷ 2 = 6,296,895.5
If the quotient is a whole number, then 2 and 6,296,895.5 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 | 12,593,791 | |
| -1 | -12,593,791 |
Now, we try dividing 12,593,791 by 3:
12,593,791 ÷ 3 = 4,197,930.3333
If the quotient is a whole number, then 3 and 4,197,930.3333 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 | 12,593,791 | |
| -1 | -12,593,791 |
Let's try dividing by 4:
12,593,791 ÷ 4 = 3,148,447.75
If the quotient is a whole number, then 4 and 3,148,447.75 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 | 12,593,791 | |
| -1 | 12,593,791 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 101 | 329 | 379 | 707 | 2,653 | 4,747 | 17,813 | 33,229 | 38,279 | 124,691 | 267,953 | 1,799,113 | 12,593,791 |
| -1 | -7 | -47 | -101 | -329 | -379 | -707 | -2,653 | -4,747 | -17,813 | -33,229 | -38,279 | -124,691 | -267,953 | -1,799,113 | -12,593,791 |
