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 30,656,593, 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 | 30,656,593 | |
| -1 | -30,656,593 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,656,593.
Example:
1 x 30,656,593 = 30,656,593
and
-1 x -30,656,593 = 30,656,593
Notice both answers equal 30,656,593
With that explanation out of the way, let's continue. Next, we take the number 30,656,593 and divide it by 2:
30,656,593 ÷ 2 = 15,328,296.5
If the quotient is a whole number, then 2 and 15,328,296.5 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 | 30,656,593 | |
| -1 | -30,656,593 |
Now, we try dividing 30,656,593 by 3:
30,656,593 ÷ 3 = 10,218,864.3333
If the quotient is a whole number, then 3 and 10,218,864.3333 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 | 30,656,593 | |
| -1 | -30,656,593 |
Let's try dividing by 4:
30,656,593 ÷ 4 = 7,664,148.25
If the quotient is a whole number, then 4 and 7,664,148.25 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 | 30,656,593 | |
| -1 | 30,656,593 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 71 | 187 | 781 | 1,207 | 2,309 | 13,277 | 25,399 | 39,253 | 163,939 | 431,783 | 1,803,329 | 2,786,963 | 30,656,593 |
| -1 | -11 | -17 | -71 | -187 | -781 | -1,207 | -2,309 | -13,277 | -25,399 | -39,253 | -163,939 | -431,783 | -1,803,329 | -2,786,963 | -30,656,593 |
