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 104,026,015, 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 | 104,026,015 | |
| -1 | -104,026,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,026,015.
Example:
1 x 104,026,015 = 104,026,015
and
-1 x -104,026,015 = 104,026,015
Notice both answers equal 104,026,015
With that explanation out of the way, let's continue. Next, we take the number 104,026,015 and divide it by 2:
104,026,015 ÷ 2 = 52,013,007.5
If the quotient is a whole number, then 2 and 52,013,007.5 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 | 104,026,015 | |
| -1 | -104,026,015 |
Now, we try dividing 104,026,015 by 3:
104,026,015 ÷ 3 = 34,675,338.3333
If the quotient is a whole number, then 3 and 34,675,338.3333 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 | 104,026,015 | |
| -1 | -104,026,015 |
Let's try dividing by 4:
104,026,015 ÷ 4 = 26,006,503.75
If the quotient is a whole number, then 4 and 26,006,503.75 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 | 104,026,015 | |
| -1 | 104,026,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 79 | 265 | 395 | 4,187 | 4,969 | 20,935 | 24,845 | 263,357 | 392,551 | 1,316,785 | 1,962,755 | 20,805,203 | 104,026,015 |
| -1 | -5 | -53 | -79 | -265 | -395 | -4,187 | -4,969 | -20,935 | -24,845 | -263,357 | -392,551 | -1,316,785 | -1,962,755 | -20,805,203 | -104,026,015 |
