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 117,220,117, 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 | 117,220,117 | |
| -1 | -117,220,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,220,117.
Example:
1 x 117,220,117 = 117,220,117
and
-1 x -117,220,117 = 117,220,117
Notice both answers equal 117,220,117
With that explanation out of the way, let's continue. Next, we take the number 117,220,117 and divide it by 2:
117,220,117 ÷ 2 = 58,610,058.5
If the quotient is a whole number, then 2 and 58,610,058.5 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 | 117,220,117 | |
| -1 | -117,220,117 |
Now, we try dividing 117,220,117 by 3:
117,220,117 ÷ 3 = 39,073,372.3333
If the quotient is a whole number, then 3 and 39,073,372.3333 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 | 117,220,117 | |
| -1 | -117,220,117 |
Let's try dividing by 4:
117,220,117 ÷ 4 = 29,305,029.25
If the quotient is a whole number, then 4 and 29,305,029.25 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 | 117,220,117 | |
| -1 | 117,220,117 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 493 | 3,451 | 33,967 | 237,769 | 577,439 | 985,043 | 4,042,073 | 6,895,301 | 16,745,731 | 117,220,117 |
| -1 | -7 | -17 | -29 | -119 | -203 | -493 | -3,451 | -33,967 | -237,769 | -577,439 | -985,043 | -4,042,073 | -6,895,301 | -16,745,731 | -117,220,117 |
