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 28,682,357, 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 | 28,682,357 | |
| -1 | -28,682,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 28,682,357.
Example:
1 x 28,682,357 = 28,682,357
and
-1 x -28,682,357 = 28,682,357
Notice both answers equal 28,682,357
With that explanation out of the way, let's continue. Next, we take the number 28,682,357 and divide it by 2:
28,682,357 ÷ 2 = 14,341,178.5
If the quotient is a whole number, then 2 and 14,341,178.5 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 | 28,682,357 | |
| -1 | -28,682,357 |
Now, we try dividing 28,682,357 by 3:
28,682,357 ÷ 3 = 9,560,785.6667
If the quotient is a whole number, then 3 and 9,560,785.6667 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 | 28,682,357 | |
| -1 | -28,682,357 |
Let's try dividing by 4:
28,682,357 ÷ 4 = 7,170,589.25
If the quotient is a whole number, then 4 and 7,170,589.25 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 | 28,682,357 | |
| -1 | 28,682,357 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 73 | 253 | 803 | 1,553 | 1,679 | 17,083 | 18,469 | 35,719 | 113,369 | 392,909 | 1,247,059 | 2,607,487 | 28,682,357 |
| -1 | -11 | -23 | -73 | -253 | -803 | -1,553 | -1,679 | -17,083 | -18,469 | -35,719 | -113,369 | -392,909 | -1,247,059 | -2,607,487 | -28,682,357 |
