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 104,432,405, 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 | 104,432,405 | |
| -1 | -104,432,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,432,405.
Example:
1 x 104,432,405 = 104,432,405
and
-1 x -104,432,405 = 104,432,405
Notice both answers equal 104,432,405
With that explanation out of the way, let's continue. Next, we take the number 104,432,405 and divide it by 2:
104,432,405 ÷ 2 = 52,216,202.5
If the quotient is a whole number, then 2 and 52,216,202.5 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 | 104,432,405 | |
| -1 | -104,432,405 |
Now, we try dividing 104,432,405 by 3:
104,432,405 ÷ 3 = 34,810,801.6667
If the quotient is a whole number, then 3 and 34,810,801.6667 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 | 104,432,405 | |
| -1 | -104,432,405 |
Let's try dividing by 4:
104,432,405 ÷ 4 = 26,108,101.25
If the quotient is a whole number, then 4 and 26,108,101.25 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 | 104,432,405 | |
| -1 | 104,432,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 271,253 | 1,356,265 | 1,898,771 | 2,983,783 | 9,493,855 | 14,918,915 | 20,886,481 | 104,432,405 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -271,253 | -1,356,265 | -1,898,771 | -2,983,783 | -9,493,855 | -14,918,915 | -20,886,481 | -104,432,405 |
