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 117,581,299, 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 | 117,581,299 | |
| -1 | -117,581,299 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 117,581,299.
Example:
1 x 117,581,299 = 117,581,299
and
-1 x -117,581,299 = 117,581,299
Notice both answers equal 117,581,299
With that explanation out of the way, let's continue. Next, we take the number 117,581,299 and divide it by 2:
117,581,299 ÷ 2 = 58,790,649.5
If the quotient is a whole number, then 2 and 58,790,649.5 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 | 117,581,299 | |
| -1 | -117,581,299 |
Now, we try dividing 117,581,299 by 3:
117,581,299 ÷ 3 = 39,193,766.3333
If the quotient is a whole number, then 3 and 39,193,766.3333 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 | 117,581,299 | |
| -1 | -117,581,299 |
Let's try dividing by 4:
117,581,299 ÷ 4 = 29,395,324.75
If the quotient is a whole number, then 4 and 29,395,324.75 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 | 117,581,299 | |
| -1 | 117,581,299 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 127 | 187 | 1,397 | 2,159 | 4,951 | 23,749 | 54,461 | 84,167 | 628,777 | 925,837 | 6,916,547 | 10,689,209 | 117,581,299 |
| -1 | -11 | -17 | -127 | -187 | -1,397 | -2,159 | -4,951 | -23,749 | -54,461 | -84,167 | -628,777 | -925,837 | -6,916,547 | -10,689,209 | -117,581,299 |
