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 117,042,725, 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 | 117,042,725 | |
| -1 | -117,042,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,042,725.
Example:
1 x 117,042,725 = 117,042,725
and
-1 x -117,042,725 = 117,042,725
Notice both answers equal 117,042,725
With that explanation out of the way, let's continue. Next, we take the number 117,042,725 and divide it by 2:
117,042,725 ÷ 2 = 58,521,362.5
If the quotient is a whole number, then 2 and 58,521,362.5 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 | 117,042,725 | |
| -1 | -117,042,725 |
Now, we try dividing 117,042,725 by 3:
117,042,725 ÷ 3 = 39,014,241.6667
If the quotient is a whole number, then 3 and 39,014,241.6667 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 | 117,042,725 | |
| -1 | -117,042,725 |
Let's try dividing by 4:
117,042,725 ÷ 4 = 29,260,681.25
If the quotient is a whole number, then 4 and 29,260,681.25 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 | 117,042,725 | |
| -1 | 117,042,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 73 | 295 | 365 | 1,087 | 1,475 | 1,825 | 4,307 | 5,435 | 21,535 | 27,175 | 64,133 | 79,351 | 107,675 | 320,665 | 396,755 | 1,603,325 | 1,983,775 | 4,681,709 | 23,408,545 | 117,042,725 |
| -1 | -5 | -25 | -59 | -73 | -295 | -365 | -1,087 | -1,475 | -1,825 | -4,307 | -5,435 | -21,535 | -27,175 | -64,133 | -79,351 | -107,675 | -320,665 | -396,755 | -1,603,325 | -1,983,775 | -4,681,709 | -23,408,545 | -117,042,725 |
