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 250,260,005, 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 | 250,260,005 | |
| -1 | -250,260,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 250,260,005.
Example:
1 x 250,260,005 = 250,260,005
and
-1 x -250,260,005 = 250,260,005
Notice both answers equal 250,260,005
With that explanation out of the way, let's continue. Next, we take the number 250,260,005 and divide it by 2:
250,260,005 ÷ 2 = 125,130,002.5
If the quotient is a whole number, then 2 and 125,130,002.5 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 | 250,260,005 | |
| -1 | -250,260,005 |
Now, we try dividing 250,260,005 by 3:
250,260,005 ÷ 3 = 83,420,001.6667
If the quotient is a whole number, then 3 and 83,420,001.6667 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 | 250,260,005 | |
| -1 | -250,260,005 |
Let's try dividing by 4:
250,260,005 ÷ 4 = 62,565,001.25
If the quotient is a whole number, then 4 and 62,565,001.25 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 | 250,260,005 | |
| -1 | 250,260,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 281 | 295 | 1,405 | 3,019 | 15,095 | 16,579 | 82,895 | 178,121 | 848,339 | 890,605 | 4,241,695 | 50,052,001 | 250,260,005 |
| -1 | -5 | -59 | -281 | -295 | -1,405 | -3,019 | -15,095 | -16,579 | -82,895 | -178,121 | -848,339 | -890,605 | -4,241,695 | -50,052,001 | -250,260,005 |
