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 105,754,705, 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 | 105,754,705 | |
| -1 | -105,754,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 105,754,705.
Example:
1 x 105,754,705 = 105,754,705
and
-1 x -105,754,705 = 105,754,705
Notice both answers equal 105,754,705
With that explanation out of the way, let's continue. Next, we take the number 105,754,705 and divide it by 2:
105,754,705 ÷ 2 = 52,877,352.5
If the quotient is a whole number, then 2 and 52,877,352.5 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 | 105,754,705 | |
| -1 | -105,754,705 |
Now, we try dividing 105,754,705 by 3:
105,754,705 ÷ 3 = 35,251,568.3333
If the quotient is a whole number, then 3 and 35,251,568.3333 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 | 105,754,705 | |
| -1 | -105,754,705 |
Let's try dividing by 4:
105,754,705 ÷ 4 = 26,438,676.25
If the quotient is a whole number, then 4 and 26,438,676.25 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 | 105,754,705 | |
| -1 | 105,754,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 177,739 | 888,695 | 1,244,173 | 3,021,563 | 6,220,865 | 15,107,815 | 21,150,941 | 105,754,705 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -177,739 | -888,695 | -1,244,173 | -3,021,563 | -6,220,865 | -15,107,815 | -21,150,941 | -105,754,705 |
