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 104,502,085, 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 | 104,502,085 | |
| -1 | -104,502,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,502,085.
Example:
1 x 104,502,085 = 104,502,085
and
-1 x -104,502,085 = 104,502,085
Notice both answers equal 104,502,085
With that explanation out of the way, let's continue. Next, we take the number 104,502,085 and divide it by 2:
104,502,085 ÷ 2 = 52,251,042.5
If the quotient is a whole number, then 2 and 52,251,042.5 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 | 104,502,085 | |
| -1 | -104,502,085 |
Now, we try dividing 104,502,085 by 3:
104,502,085 ÷ 3 = 34,834,028.3333
If the quotient is a whole number, then 3 and 34,834,028.3333 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 | 104,502,085 | |
| -1 | -104,502,085 |
Let's try dividing by 4:
104,502,085 ÷ 4 = 26,125,521.25
If the quotient is a whole number, then 4 and 26,125,521.25 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 | 104,502,085 | |
| -1 | 104,502,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 107 | 155 | 535 | 3,317 | 6,301 | 16,585 | 31,505 | 195,331 | 674,207 | 976,655 | 3,371,035 | 20,900,417 | 104,502,085 |
| -1 | -5 | -31 | -107 | -155 | -535 | -3,317 | -6,301 | -16,585 | -31,505 | -195,331 | -674,207 | -976,655 | -3,371,035 | -20,900,417 | -104,502,085 |
