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 305,174,705, 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 | 305,174,705 | |
| -1 | -305,174,705 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,174,705.
Example:
1 x 305,174,705 = 305,174,705
and
-1 x -305,174,705 = 305,174,705
Notice both answers equal 305,174,705
With that explanation out of the way, let's continue. Next, we take the number 305,174,705 and divide it by 2:
305,174,705 ÷ 2 = 152,587,352.5
If the quotient is a whole number, then 2 and 152,587,352.5 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 | 305,174,705 | |
| -1 | -305,174,705 |
Now, we try dividing 305,174,705 by 3:
305,174,705 ÷ 3 = 101,724,901.6667
If the quotient is a whole number, then 3 and 101,724,901.6667 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 | 305,174,705 | |
| -1 | -305,174,705 |
Let's try dividing by 4:
305,174,705 ÷ 4 = 76,293,676.25
If the quotient is a whole number, then 4 and 76,293,676.25 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 | 305,174,705 | |
| -1 | 305,174,705 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 37 | 55 | 121 | 185 | 407 | 605 | 2,035 | 4,477 | 13,633 | 22,385 | 68,165 | 149,963 | 504,421 | 749,815 | 1,649,593 | 2,522,105 | 5,548,631 | 8,247,965 | 27,743,155 | 61,034,941 | 305,174,705 |
| -1 | -5 | -11 | -37 | -55 | -121 | -185 | -407 | -605 | -2,035 | -4,477 | -13,633 | -22,385 | -68,165 | -149,963 | -504,421 | -749,815 | -1,649,593 | -2,522,105 | -5,548,631 | -8,247,965 | -27,743,155 | -61,034,941 | -305,174,705 |
