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 117,347,725, 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 | 117,347,725 | |
| -1 | -117,347,725 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,347,725.
Example:
1 x 117,347,725 = 117,347,725
and
-1 x -117,347,725 = 117,347,725
Notice both answers equal 117,347,725
With that explanation out of the way, let's continue. Next, we take the number 117,347,725 and divide it by 2:
117,347,725 ÷ 2 = 58,673,862.5
If the quotient is a whole number, then 2 and 58,673,862.5 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 | 117,347,725 | |
| -1 | -117,347,725 |
Now, we try dividing 117,347,725 by 3:
117,347,725 ÷ 3 = 39,115,908.3333
If the quotient is a whole number, then 3 and 39,115,908.3333 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 | 117,347,725 | |
| -1 | -117,347,725 |
Let's try dividing by 4:
117,347,725 ÷ 4 = 29,336,931.25
If the quotient is a whole number, then 4 and 29,336,931.25 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 | 117,347,725 | |
| -1 | 117,347,725 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 23 | 25 | 55 | 115 | 253 | 275 | 575 | 1,265 | 6,325 | 18,553 | 92,765 | 204,083 | 426,719 | 463,825 | 1,020,415 | 2,133,595 | 4,693,909 | 5,102,075 | 10,667,975 | 23,469,545 | 117,347,725 |
| -1 | -5 | -11 | -23 | -25 | -55 | -115 | -253 | -275 | -575 | -1,265 | -6,325 | -18,553 | -92,765 | -204,083 | -426,719 | -463,825 | -1,020,415 | -2,133,595 | -4,693,909 | -5,102,075 | -10,667,975 | -23,469,545 | -117,347,725 |
