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 411,156,055, 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 | 411,156,055 | |
| -1 | -411,156,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 411,156,055.
Example:
1 x 411,156,055 = 411,156,055
and
-1 x -411,156,055 = 411,156,055
Notice both answers equal 411,156,055
With that explanation out of the way, let's continue. Next, we take the number 411,156,055 and divide it by 2:
411,156,055 ÷ 2 = 205,578,027.5
If the quotient is a whole number, then 2 and 205,578,027.5 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 | 411,156,055 | |
| -1 | -411,156,055 |
Now, we try dividing 411,156,055 by 3:
411,156,055 ÷ 3 = 137,052,018.3333
If the quotient is a whole number, then 3 and 137,052,018.3333 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 | 411,156,055 | |
| -1 | -411,156,055 |
Let's try dividing by 4:
411,156,055 ÷ 4 = 102,789,013.75
If the quotient is a whole number, then 4 and 102,789,013.75 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 | 411,156,055 | |
| -1 | 411,156,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 859 | 3,301 | 4,295 | 16,505 | 24,911 | 95,729 | 124,555 | 478,645 | 2,835,559 | 14,177,795 | 82,231,211 | 411,156,055 |
| -1 | -5 | -29 | -145 | -859 | -3,301 | -4,295 | -16,505 | -24,911 | -95,729 | -124,555 | -478,645 | -2,835,559 | -14,177,795 | -82,231,211 | -411,156,055 |
