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 478,658,125, 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 | 478,658,125 | |
| -1 | -478,658,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 478,658,125.
Example:
1 x 478,658,125 = 478,658,125
and
-1 x -478,658,125 = 478,658,125
Notice both answers equal 478,658,125
With that explanation out of the way, let's continue. Next, we take the number 478,658,125 and divide it by 2:
478,658,125 ÷ 2 = 239,329,062.5
If the quotient is a whole number, then 2 and 239,329,062.5 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 | 478,658,125 | |
| -1 | -478,658,125 |
Now, we try dividing 478,658,125 by 3:
478,658,125 ÷ 3 = 159,552,708.3333
If the quotient is a whole number, then 3 and 159,552,708.3333 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 | 478,658,125 | |
| -1 | -478,658,125 |
Let's try dividing by 4:
478,658,125 ÷ 4 = 119,664,531.25
If the quotient is a whole number, then 4 and 119,664,531.25 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 | 478,658,125 | |
| -1 | 478,658,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 625 | 1,375 | 6,875 | 69,623 | 348,115 | 765,853 | 1,740,575 | 3,829,265 | 8,702,875 | 19,146,325 | 43,514,375 | 95,731,625 | 478,658,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -625 | -1,375 | -6,875 | -69,623 | -348,115 | -765,853 | -1,740,575 | -3,829,265 | -8,702,875 | -19,146,325 | -43,514,375 | -95,731,625 | -478,658,125 |
