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 110,705,905, 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 | 110,705,905 | |
| -1 | -110,705,905 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,705,905.
Example:
1 x 110,705,905 = 110,705,905
and
-1 x -110,705,905 = 110,705,905
Notice both answers equal 110,705,905
With that explanation out of the way, let's continue. Next, we take the number 110,705,905 and divide it by 2:
110,705,905 ÷ 2 = 55,352,952.5
If the quotient is a whole number, then 2 and 55,352,952.5 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 | 110,705,905 | |
| -1 | -110,705,905 |
Now, we try dividing 110,705,905 by 3:
110,705,905 ÷ 3 = 36,901,968.3333
If the quotient is a whole number, then 3 and 36,901,968.3333 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 | 110,705,905 | |
| -1 | -110,705,905 |
Let's try dividing by 4:
110,705,905 ÷ 4 = 27,676,476.25
If the quotient is a whole number, then 4 and 27,676,476.25 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 | 110,705,905 | |
| -1 | 110,705,905 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 263 | 1,315 | 2,903 | 7,627 | 14,515 | 38,135 | 84,187 | 420,935 | 763,489 | 3,817,445 | 22,141,181 | 110,705,905 |
| -1 | -5 | -29 | -145 | -263 | -1,315 | -2,903 | -7,627 | -14,515 | -38,135 | -84,187 | -420,935 | -763,489 | -3,817,445 | -22,141,181 | -110,705,905 |
