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 115,658,675, 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 | 115,658,675 | |
| -1 | -115,658,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 115,658,675.
Example:
1 x 115,658,675 = 115,658,675
and
-1 x -115,658,675 = 115,658,675
Notice both answers equal 115,658,675
With that explanation out of the way, let's continue. Next, we take the number 115,658,675 and divide it by 2:
115,658,675 ÷ 2 = 57,829,337.5
If the quotient is a whole number, then 2 and 57,829,337.5 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 | 115,658,675 | |
| -1 | -115,658,675 |
Now, we try dividing 115,658,675 by 3:
115,658,675 ÷ 3 = 38,552,891.6667
If the quotient is a whole number, then 3 and 38,552,891.6667 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 | 115,658,675 | |
| -1 | -115,658,675 |
Let's try dividing by 4:
115,658,675 ÷ 4 = 28,914,668.75
If the quotient is a whole number, then 4 and 28,914,668.75 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 | 115,658,675 | |
| -1 | 115,658,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 31 | 55 | 155 | 275 | 341 | 775 | 1,705 | 8,525 | 13,567 | 67,835 | 149,237 | 339,175 | 420,577 | 746,185 | 2,102,885 | 3,730,925 | 4,626,347 | 10,514,425 | 23,131,735 | 115,658,675 |
| -1 | -5 | -11 | -25 | -31 | -55 | -155 | -275 | -341 | -775 | -1,705 | -8,525 | -13,567 | -67,835 | -149,237 | -339,175 | -420,577 | -746,185 | -2,102,885 | -3,730,925 | -4,626,347 | -10,514,425 | -23,131,735 | -115,658,675 |
