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 250,034,309, 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 | 250,034,309 | |
| -1 | -250,034,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,034,309.
Example:
1 x 250,034,309 = 250,034,309
and
-1 x -250,034,309 = 250,034,309
Notice both answers equal 250,034,309
With that explanation out of the way, let's continue. Next, we take the number 250,034,309 and divide it by 2:
250,034,309 ÷ 2 = 125,017,154.5
If the quotient is a whole number, then 2 and 125,017,154.5 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 | 250,034,309 | |
| -1 | -250,034,309 |
Now, we try dividing 250,034,309 by 3:
250,034,309 ÷ 3 = 83,344,769.6667
If the quotient is a whole number, then 3 and 83,344,769.6667 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 | 250,034,309 | |
| -1 | -250,034,309 |
Let's try dividing by 4:
250,034,309 ÷ 4 = 62,508,577.25
If the quotient is a whole number, then 4 and 62,508,577.25 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 | 250,034,309 | |
| -1 | 250,034,309 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 113 | 343 | 791 | 5,537 | 6,451 | 38,759 | 45,157 | 316,099 | 728,963 | 2,212,693 | 5,102,741 | 35,719,187 | 250,034,309 |
| -1 | -7 | -49 | -113 | -343 | -791 | -5,537 | -6,451 | -38,759 | -45,157 | -316,099 | -728,963 | -2,212,693 | -5,102,741 | -35,719,187 | -250,034,309 |
