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 176,307,115, 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 | 176,307,115 | |
| -1 | -176,307,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 176,307,115.
Example:
1 x 176,307,115 = 176,307,115
and
-1 x -176,307,115 = 176,307,115
Notice both answers equal 176,307,115
With that explanation out of the way, let's continue. Next, we take the number 176,307,115 and divide it by 2:
176,307,115 ÷ 2 = 88,153,557.5
If the quotient is a whole number, then 2 and 88,153,557.5 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 | 176,307,115 | |
| -1 | -176,307,115 |
Now, we try dividing 176,307,115 by 3:
176,307,115 ÷ 3 = 58,769,038.3333
If the quotient is a whole number, then 3 and 58,769,038.3333 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 | 176,307,115 | |
| -1 | -176,307,115 |
Let's try dividing by 4:
176,307,115 ÷ 4 = 44,076,778.75
If the quotient is a whole number, then 4 and 44,076,778.75 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 | 176,307,115 | |
| -1 | 176,307,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 127 | 505 | 635 | 2,749 | 12,827 | 13,745 | 64,135 | 277,649 | 349,123 | 1,388,245 | 1,745,615 | 35,261,423 | 176,307,115 |
| -1 | -5 | -101 | -127 | -505 | -635 | -2,749 | -12,827 | -13,745 | -64,135 | -277,649 | -349,123 | -1,388,245 | -1,745,615 | -35,261,423 | -176,307,115 |
