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 117,018,161, 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 | 117,018,161 | |
| -1 | -117,018,161 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,018,161.
Example:
1 x 117,018,161 = 117,018,161
and
-1 x -117,018,161 = 117,018,161
Notice both answers equal 117,018,161
With that explanation out of the way, let's continue. Next, we take the number 117,018,161 and divide it by 2:
117,018,161 ÷ 2 = 58,509,080.5
If the quotient is a whole number, then 2 and 58,509,080.5 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 | 117,018,161 | |
| -1 | -117,018,161 |
Now, we try dividing 117,018,161 by 3:
117,018,161 ÷ 3 = 39,006,053.6667
If the quotient is a whole number, then 3 and 39,006,053.6667 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 | 117,018,161 | |
| -1 | -117,018,161 |
Let's try dividing by 4:
117,018,161 ÷ 4 = 29,254,540.25
If the quotient is a whole number, then 4 and 29,254,540.25 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 | 117,018,161 | |
| -1 | 117,018,161 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 37 | 377 | 481 | 1,073 | 8,389 | 13,949 | 109,057 | 243,281 | 310,393 | 3,162,653 | 4,035,109 | 9,001,397 | 117,018,161 |
| -1 | -13 | -29 | -37 | -377 | -481 | -1,073 | -8,389 | -13,949 | -109,057 | -243,281 | -310,393 | -3,162,653 | -4,035,109 | -9,001,397 | -117,018,161 |
