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 250,454,645, 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 | 250,454,645 | |
| -1 | -250,454,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,454,645.
Example:
1 x 250,454,645 = 250,454,645
and
-1 x -250,454,645 = 250,454,645
Notice both answers equal 250,454,645
With that explanation out of the way, let's continue. Next, we take the number 250,454,645 and divide it by 2:
250,454,645 ÷ 2 = 125,227,322.5
If the quotient is a whole number, then 2 and 125,227,322.5 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 | 250,454,645 | |
| -1 | -250,454,645 |
Now, we try dividing 250,454,645 by 3:
250,454,645 ÷ 3 = 83,484,881.6667
If the quotient is a whole number, then 3 and 83,484,881.6667 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 | 250,454,645 | |
| -1 | -250,454,645 |
Let's try dividing by 4:
250,454,645 ÷ 4 = 62,613,661.25
If the quotient is a whole number, then 4 and 62,613,661.25 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 | 250,454,645 | |
| -1 | 250,454,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 223 | 1,115 | 1,561 | 7,805 | 32,089 | 160,445 | 224,623 | 1,123,115 | 7,155,847 | 35,779,235 | 50,090,929 | 250,454,645 |
| -1 | -5 | -7 | -35 | -223 | -1,115 | -1,561 | -7,805 | -32,089 | -160,445 | -224,623 | -1,123,115 | -7,155,847 | -35,779,235 | -50,090,929 | -250,454,645 |
