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 181,605,677, 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 | 181,605,677 | |
| -1 | -181,605,677 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 181,605,677.
Example:
1 x 181,605,677 = 181,605,677
and
-1 x -181,605,677 = 181,605,677
Notice both answers equal 181,605,677
With that explanation out of the way, let's continue. Next, we take the number 181,605,677 and divide it by 2:
181,605,677 ÷ 2 = 90,802,838.5
If the quotient is a whole number, then 2 and 90,802,838.5 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 | 181,605,677 | |
| -1 | -181,605,677 |
Now, we try dividing 181,605,677 by 3:
181,605,677 ÷ 3 = 60,535,225.6667
If the quotient is a whole number, then 3 and 60,535,225.6667 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 | 181,605,677 | |
| -1 | -181,605,677 |
Let's try dividing by 4:
181,605,677 ÷ 4 = 45,401,419.25
If the quotient is a whole number, then 4 and 45,401,419.25 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 | 181,605,677 | |
| -1 | 181,605,677 |
If you did it right, you will end up with this table:
| 1 | 11 | 23 | 73 | 253 | 803 | 1,679 | 9,833 | 18,469 | 108,163 | 226,159 | 717,809 | 2,487,749 | 7,895,899 | 16,509,607 | 181,605,677 |
| -1 | -11 | -23 | -73 | -253 | -803 | -1,679 | -9,833 | -18,469 | -108,163 | -226,159 | -717,809 | -2,487,749 | -7,895,899 | -16,509,607 | -181,605,677 |
