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 116,415,887, 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 | 116,415,887 | |
| -1 | -116,415,887 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,415,887.
Example:
1 x 116,415,887 = 116,415,887
and
-1 x -116,415,887 = 116,415,887
Notice both answers equal 116,415,887
With that explanation out of the way, let's continue. Next, we take the number 116,415,887 and divide it by 2:
116,415,887 ÷ 2 = 58,207,943.5
If the quotient is a whole number, then 2 and 58,207,943.5 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 | 116,415,887 | |
| -1 | -116,415,887 |
Now, we try dividing 116,415,887 by 3:
116,415,887 ÷ 3 = 38,805,295.6667
If the quotient is a whole number, then 3 and 38,805,295.6667 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 | 116,415,887 | |
| -1 | -116,415,887 |
Let's try dividing by 4:
116,415,887 ÷ 4 = 29,103,971.75
If the quotient is a whole number, then 4 and 29,103,971.75 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 | 116,415,887 | |
| -1 | 116,415,887 |
If you did it right, you will end up with this table:
| 1 | 7 | 137 | 233 | 521 | 959 | 1,631 | 3,647 | 31,921 | 71,377 | 121,393 | 223,447 | 499,639 | 849,751 | 16,630,841 | 116,415,887 |
| -1 | -7 | -137 | -233 | -521 | -959 | -1,631 | -3,647 | -31,921 | -71,377 | -121,393 | -223,447 | -499,639 | -849,751 | -16,630,841 | -116,415,887 |
