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 117,163,081, 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 | 117,163,081 | |
| -1 | -117,163,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,163,081.
Example:
1 x 117,163,081 = 117,163,081
and
-1 x -117,163,081 = 117,163,081
Notice both answers equal 117,163,081
With that explanation out of the way, let's continue. Next, we take the number 117,163,081 and divide it by 2:
117,163,081 ÷ 2 = 58,581,540.5
If the quotient is a whole number, then 2 and 58,581,540.5 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 | 117,163,081 | |
| -1 | -117,163,081 |
Now, we try dividing 117,163,081 by 3:
117,163,081 ÷ 3 = 39,054,360.3333
If the quotient is a whole number, then 3 and 39,054,360.3333 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 | 117,163,081 | |
| -1 | -117,163,081 |
Let's try dividing by 4:
117,163,081 ÷ 4 = 29,290,770.25
If the quotient is a whole number, then 4 and 29,290,770.25 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 | 117,163,081 | |
| -1 | 117,163,081 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 161 | 263 | 1,841 | 2,767 | 6,049 | 19,369 | 42,343 | 63,641 | 445,487 | 727,721 | 5,094,047 | 16,737,583 | 117,163,081 |
| -1 | -7 | -23 | -161 | -263 | -1,841 | -2,767 | -6,049 | -19,369 | -42,343 | -63,641 | -445,487 | -727,721 | -5,094,047 | -16,737,583 | -117,163,081 |
