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 16,582,531, 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 | 16,582,531 | |
| -1 | -16,582,531 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,582,531.
Example:
1 x 16,582,531 = 16,582,531
and
-1 x -16,582,531 = 16,582,531
Notice both answers equal 16,582,531
With that explanation out of the way, let's continue. Next, we take the number 16,582,531 and divide it by 2:
16,582,531 ÷ 2 = 8,291,265.5
If the quotient is a whole number, then 2 and 8,291,265.5 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 | 16,582,531 | |
| -1 | -16,582,531 |
Now, we try dividing 16,582,531 by 3:
16,582,531 ÷ 3 = 5,527,510.3333
If the quotient is a whole number, then 3 and 5,527,510.3333 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 | 16,582,531 | |
| -1 | -16,582,531 |
Let's try dividing by 4:
16,582,531 ÷ 4 = 4,145,632.75
If the quotient is a whole number, then 4 and 4,145,632.75 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 | 16,582,531 | |
| -1 | 16,582,531 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 119 | 289 | 833 | 1,171 | 2,023 | 8,197 | 14,161 | 19,907 | 57,379 | 139,349 | 338,419 | 975,443 | 2,368,933 | 16,582,531 |
| -1 | -7 | -17 | -49 | -119 | -289 | -833 | -1,171 | -2,023 | -8,197 | -14,161 | -19,907 | -57,379 | -139,349 | -338,419 | -975,443 | -2,368,933 | -16,582,531 |
