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 116,531,519, 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 | 116,531,519 | |
| -1 | -116,531,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,531,519.
Example:
1 x 116,531,519 = 116,531,519
and
-1 x -116,531,519 = 116,531,519
Notice both answers equal 116,531,519
With that explanation out of the way, let's continue. Next, we take the number 116,531,519 and divide it by 2:
116,531,519 ÷ 2 = 58,265,759.5
If the quotient is a whole number, then 2 and 58,265,759.5 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 | 116,531,519 | |
| -1 | -116,531,519 |
Now, we try dividing 116,531,519 by 3:
116,531,519 ÷ 3 = 38,843,839.6667
If the quotient is a whole number, then 3 and 38,843,839.6667 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 | 116,531,519 | |
| -1 | -116,531,519 |
Let's try dividing by 4:
116,531,519 ÷ 4 = 29,132,879.75
If the quotient is a whole number, then 4 and 29,132,879.75 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 | 116,531,519 | |
| -1 | 116,531,519 |
If you did it right, you will end up with this table:
| 1 | 13 | 71 | 251 | 503 | 923 | 3,263 | 6,539 | 17,821 | 35,713 | 126,253 | 231,673 | 464,269 | 1,641,289 | 8,963,963 | 116,531,519 |
| -1 | -13 | -71 | -251 | -503 | -923 | -3,263 | -6,539 | -17,821 | -35,713 | -126,253 | -231,673 | -464,269 | -1,641,289 | -8,963,963 | -116,531,519 |
