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 117,853,177, 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 | 117,853,177 | |
| -1 | -117,853,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,853,177.
Example:
1 x 117,853,177 = 117,853,177
and
-1 x -117,853,177 = 117,853,177
Notice both answers equal 117,853,177
With that explanation out of the way, let's continue. Next, we take the number 117,853,177 and divide it by 2:
117,853,177 ÷ 2 = 58,926,588.5
If the quotient is a whole number, then 2 and 58,926,588.5 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 | 117,853,177 | |
| -1 | -117,853,177 |
Now, we try dividing 117,853,177 by 3:
117,853,177 ÷ 3 = 39,284,392.3333
If the quotient is a whole number, then 3 and 39,284,392.3333 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 | 117,853,177 | |
| -1 | -117,853,177 |
Let's try dividing by 4:
117,853,177 ÷ 4 = 29,463,294.25
If the quotient is a whole number, then 4 and 29,463,294.25 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 | 117,853,177 | |
| -1 | 117,853,177 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 89 | 481 | 1,157 | 2,753 | 3,293 | 35,789 | 42,809 | 101,861 | 245,017 | 1,324,193 | 3,185,221 | 9,065,629 | 117,853,177 |
| -1 | -13 | -37 | -89 | -481 | -1,157 | -2,753 | -3,293 | -35,789 | -42,809 | -101,861 | -245,017 | -1,324,193 | -3,185,221 | -9,065,629 | -117,853,177 |
