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 104,115,143, 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 | 104,115,143 | |
| -1 | -104,115,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,115,143.
Example:
1 x 104,115,143 = 104,115,143
and
-1 x -104,115,143 = 104,115,143
Notice both answers equal 104,115,143
With that explanation out of the way, let's continue. Next, we take the number 104,115,143 and divide it by 2:
104,115,143 ÷ 2 = 52,057,571.5
If the quotient is a whole number, then 2 and 52,057,571.5 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 | 104,115,143 | |
| -1 | -104,115,143 |
Now, we try dividing 104,115,143 by 3:
104,115,143 ÷ 3 = 34,705,047.6667
If the quotient is a whole number, then 3 and 34,705,047.6667 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 | 104,115,143 | |
| -1 | -104,115,143 |
Let's try dividing by 4:
104,115,143 ÷ 4 = 26,028,785.75
If the quotient is a whole number, then 4 and 26,028,785.75 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 | 104,115,143 | |
| -1 | 104,115,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 101 | 341 | 1,111 | 3,023 | 3,131 | 33,253 | 34,441 | 93,713 | 305,323 | 1,030,843 | 3,358,553 | 9,465,013 | 104,115,143 |
| -1 | -11 | -31 | -101 | -341 | -1,111 | -3,023 | -3,131 | -33,253 | -34,441 | -93,713 | -305,323 | -1,030,843 | -3,358,553 | -9,465,013 | -104,115,143 |
