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 116,661,539, 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 | 116,661,539 | |
| -1 | -116,661,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,661,539.
Example:
1 x 116,661,539 = 116,661,539
and
-1 x -116,661,539 = 116,661,539
Notice both answers equal 116,661,539
With that explanation out of the way, let's continue. Next, we take the number 116,661,539 and divide it by 2:
116,661,539 ÷ 2 = 58,330,769.5
If the quotient is a whole number, then 2 and 58,330,769.5 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 | 116,661,539 | |
| -1 | -116,661,539 |
Now, we try dividing 116,661,539 by 3:
116,661,539 ÷ 3 = 38,887,179.6667
If the quotient is a whole number, then 3 and 38,887,179.6667 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 | 116,661,539 | |
| -1 | -116,661,539 |
Let's try dividing by 4:
116,661,539 ÷ 4 = 29,165,384.75
If the quotient is a whole number, then 4 and 29,165,384.75 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 | 116,661,539 | |
| -1 | 116,661,539 |
If you did it right, you will end up with this table:
| 1 | 19 | 67 | 113 | 811 | 1,273 | 2,147 | 7,571 | 15,409 | 54,337 | 91,643 | 143,849 | 1,032,403 | 1,741,217 | 6,140,081 | 116,661,539 |
| -1 | -19 | -67 | -113 | -811 | -1,273 | -2,147 | -7,571 | -15,409 | -54,337 | -91,643 | -143,849 | -1,032,403 | -1,741,217 | -6,140,081 | -116,661,539 |
