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 116,663,645, 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 | 116,663,645 | |
| -1 | -116,663,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,663,645.
Example:
1 x 116,663,645 = 116,663,645
and
-1 x -116,663,645 = 116,663,645
Notice both answers equal 116,663,645
With that explanation out of the way, let's continue. Next, we take the number 116,663,645 and divide it by 2:
116,663,645 ÷ 2 = 58,331,822.5
If the quotient is a whole number, then 2 and 58,331,822.5 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 | 116,663,645 | |
| -1 | -116,663,645 |
Now, we try dividing 116,663,645 by 3:
116,663,645 ÷ 3 = 38,887,881.6667
If the quotient is a whole number, then 3 and 38,887,881.6667 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 | 116,663,645 | |
| -1 | -116,663,645 |
Let's try dividing by 4:
116,663,645 ÷ 4 = 29,165,911.25
If the quotient is a whole number, then 4 and 29,165,911.25 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 | 116,663,645 | |
| -1 | 116,663,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 79 | 395 | 553 | 2,765 | 42,193 | 210,965 | 295,351 | 1,476,755 | 3,333,247 | 16,666,235 | 23,332,729 | 116,663,645 |
| -1 | -5 | -7 | -35 | -79 | -395 | -553 | -2,765 | -42,193 | -210,965 | -295,351 | -1,476,755 | -3,333,247 | -16,666,235 | -23,332,729 | -116,663,645 |
