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 176,511,005, 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 | 176,511,005 | |
| -1 | -176,511,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,511,005.
Example:
1 x 176,511,005 = 176,511,005
and
-1 x -176,511,005 = 176,511,005
Notice both answers equal 176,511,005
With that explanation out of the way, let's continue. Next, we take the number 176,511,005 and divide it by 2:
176,511,005 ÷ 2 = 88,255,502.5
If the quotient is a whole number, then 2 and 88,255,502.5 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 | 176,511,005 | |
| -1 | -176,511,005 |
Now, we try dividing 176,511,005 by 3:
176,511,005 ÷ 3 = 58,837,001.6667
If the quotient is a whole number, then 3 and 58,837,001.6667 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 | 176,511,005 | |
| -1 | -176,511,005 |
Let's try dividing by 4:
176,511,005 ÷ 4 = 44,127,751.25
If the quotient is a whole number, then 4 and 44,127,751.25 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 | 176,511,005 | |
| -1 | 176,511,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 179 | 895 | 1,969 | 9,845 | 17,929 | 89,645 | 197,219 | 986,095 | 3,209,291 | 16,046,455 | 35,302,201 | 176,511,005 |
| -1 | -5 | -11 | -55 | -179 | -895 | -1,969 | -9,845 | -17,929 | -89,645 | -197,219 | -986,095 | -3,209,291 | -16,046,455 | -35,302,201 | -176,511,005 |
