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 104,870,705, 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 | 104,870,705 | |
| -1 | -104,870,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,870,705.
Example:
1 x 104,870,705 = 104,870,705
and
-1 x -104,870,705 = 104,870,705
Notice both answers equal 104,870,705
With that explanation out of the way, let's continue. Next, we take the number 104,870,705 and divide it by 2:
104,870,705 ÷ 2 = 52,435,352.5
If the quotient is a whole number, then 2 and 52,435,352.5 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 | 104,870,705 | |
| -1 | -104,870,705 |
Now, we try dividing 104,870,705 by 3:
104,870,705 ÷ 3 = 34,956,901.6667
If the quotient is a whole number, then 3 and 34,956,901.6667 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 | 104,870,705 | |
| -1 | -104,870,705 |
Let's try dividing by 4:
104,870,705 ÷ 4 = 26,217,676.25
If the quotient is a whole number, then 4 and 26,217,676.25 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 | 104,870,705 | |
| -1 | 104,870,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 73 | 85 | 365 | 1,241 | 6,205 | 16,901 | 84,505 | 287,317 | 1,233,773 | 1,436,585 | 6,168,865 | 20,974,141 | 104,870,705 |
| -1 | -5 | -17 | -73 | -85 | -365 | -1,241 | -6,205 | -16,901 | -84,505 | -287,317 | -1,233,773 | -1,436,585 | -6,168,865 | -20,974,141 | -104,870,705 |
