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 485,324,657, 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 | 485,324,657 | |
| -1 | -485,324,657 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 485,324,657.
Example:
1 x 485,324,657 = 485,324,657
and
-1 x -485,324,657 = 485,324,657
Notice both answers equal 485,324,657
With that explanation out of the way, let's continue. Next, we take the number 485,324,657 and divide it by 2:
485,324,657 ÷ 2 = 242,662,328.5
If the quotient is a whole number, then 2 and 242,662,328.5 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 | 485,324,657 | |
| -1 | -485,324,657 |
Now, we try dividing 485,324,657 by 3:
485,324,657 ÷ 3 = 161,774,885.6667
If the quotient is a whole number, then 3 and 161,774,885.6667 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 | 485,324,657 | |
| -1 | -485,324,657 |
Let's try dividing by 4:
485,324,657 ÷ 4 = 121,331,164.25
If the quotient is a whole number, then 4 and 121,331,164.25 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 | 485,324,657 | |
| -1 | 485,324,657 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 53 | 551 | 1,007 | 1,537 | 16,619 | 29,203 | 315,761 | 481,951 | 880,807 | 9,157,069 | 16,735,333 | 25,543,403 | 485,324,657 |
| -1 | -19 | -29 | -53 | -551 | -1,007 | -1,537 | -16,619 | -29,203 | -315,761 | -481,951 | -880,807 | -9,157,069 | -16,735,333 | -25,543,403 | -485,324,657 |
