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 116,777,485, 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 | 116,777,485 | |
| -1 | -116,777,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,777,485.
Example:
1 x 116,777,485 = 116,777,485
and
-1 x -116,777,485 = 116,777,485
Notice both answers equal 116,777,485
With that explanation out of the way, let's continue. Next, we take the number 116,777,485 and divide it by 2:
116,777,485 ÷ 2 = 58,388,742.5
If the quotient is a whole number, then 2 and 58,388,742.5 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 | 116,777,485 | |
| -1 | -116,777,485 |
Now, we try dividing 116,777,485 by 3:
116,777,485 ÷ 3 = 38,925,828.3333
If the quotient is a whole number, then 3 and 38,925,828.3333 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 | 116,777,485 | |
| -1 | -116,777,485 |
Let's try dividing by 4:
116,777,485 ÷ 4 = 29,194,371.25
If the quotient is a whole number, then 4 and 29,194,371.25 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 | 116,777,485 | |
| -1 | 116,777,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 671 | 3,355 | 34,807 | 174,035 | 382,877 | 1,914,385 | 2,123,227 | 10,616,135 | 23,355,497 | 116,777,485 |
| -1 | -5 | -11 | -55 | -61 | -305 | -671 | -3,355 | -34,807 | -174,035 | -382,877 | -1,914,385 | -2,123,227 | -10,616,135 | -23,355,497 | -116,777,485 |
