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 104,411,321, 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 | 104,411,321 | |
| -1 | -104,411,321 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,411,321.
Example:
1 x 104,411,321 = 104,411,321
and
-1 x -104,411,321 = 104,411,321
Notice both answers equal 104,411,321
With that explanation out of the way, let's continue. Next, we take the number 104,411,321 and divide it by 2:
104,411,321 ÷ 2 = 52,205,660.5
If the quotient is a whole number, then 2 and 52,205,660.5 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 | 104,411,321 | |
| -1 | -104,411,321 |
Now, we try dividing 104,411,321 by 3:
104,411,321 ÷ 3 = 34,803,773.6667
If the quotient is a whole number, then 3 and 34,803,773.6667 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 | 104,411,321 | |
| -1 | -104,411,321 |
Let's try dividing by 4:
104,411,321 ÷ 4 = 26,102,830.25
If the quotient is a whole number, then 4 and 26,102,830.25 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 | 104,411,321 | |
| -1 | 104,411,321 |
If you did it right, you will end up with this table:
| 1 | 7 | 61 | 427 | 439 | 557 | 3,073 | 3,899 | 26,779 | 33,977 | 187,453 | 237,839 | 244,523 | 1,711,661 | 14,915,903 | 104,411,321 |
| -1 | -7 | -61 | -427 | -439 | -557 | -3,073 | -3,899 | -26,779 | -33,977 | -187,453 | -237,839 | -244,523 | -1,711,661 | -14,915,903 | -104,411,321 |
