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 176,261,005, 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 | 176,261,005 | |
| -1 | -176,261,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,261,005.
Example:
1 x 176,261,005 = 176,261,005
and
-1 x -176,261,005 = 176,261,005
Notice both answers equal 176,261,005
With that explanation out of the way, let's continue. Next, we take the number 176,261,005 and divide it by 2:
176,261,005 ÷ 2 = 88,130,502.5
If the quotient is a whole number, then 2 and 88,130,502.5 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 | 176,261,005 | |
| -1 | -176,261,005 |
Now, we try dividing 176,261,005 by 3:
176,261,005 ÷ 3 = 58,753,668.3333
If the quotient is a whole number, then 3 and 58,753,668.3333 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 | 176,261,005 | |
| -1 | -176,261,005 |
Let's try dividing by 4:
176,261,005 ÷ 4 = 44,065,251.25
If the quotient is a whole number, then 4 and 44,065,251.25 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 | 176,261,005 | |
| -1 | 176,261,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 233 | 1,165 | 4,427 | 7,963 | 22,135 | 39,815 | 151,297 | 756,485 | 1,855,379 | 9,276,895 | 35,252,201 | 176,261,005 |
| -1 | -5 | -19 | -95 | -233 | -1,165 | -4,427 | -7,963 | -22,135 | -39,815 | -151,297 | -756,485 | -1,855,379 | -9,276,895 | -35,252,201 | -176,261,005 |
