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 181,010,081, 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 | 181,010,081 | |
| -1 | -181,010,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 181,010,081.
Example:
1 x 181,010,081 = 181,010,081
and
-1 x -181,010,081 = 181,010,081
Notice both answers equal 181,010,081
With that explanation out of the way, let's continue. Next, we take the number 181,010,081 and divide it by 2:
181,010,081 ÷ 2 = 90,505,040.5
If the quotient is a whole number, then 2 and 90,505,040.5 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 | 181,010,081 | |
| -1 | -181,010,081 |
Now, we try dividing 181,010,081 by 3:
181,010,081 ÷ 3 = 60,336,693.6667
If the quotient is a whole number, then 3 and 60,336,693.6667 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 | 181,010,081 | |
| -1 | -181,010,081 |
Let's try dividing by 4:
181,010,081 ÷ 4 = 45,252,520.25
If the quotient is a whole number, then 4 and 45,252,520.25 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 | 181,010,081 | |
| -1 | 181,010,081 |
If you did it right, you will end up with this table:
| 1 | 7 | 67 | 107 | 469 | 749 | 3,607 | 7,169 | 25,249 | 50,183 | 241,669 | 385,949 | 1,691,683 | 2,701,643 | 25,858,583 | 181,010,081 |
| -1 | -7 | -67 | -107 | -469 | -749 | -3,607 | -7,169 | -25,249 | -50,183 | -241,669 | -385,949 | -1,691,683 | -2,701,643 | -25,858,583 | -181,010,081 |
