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 116,675,981, 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 | 116,675,981 | |
| -1 | -116,675,981 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 116,675,981.
Example:
1 x 116,675,981 = 116,675,981
and
-1 x -116,675,981 = 116,675,981
Notice both answers equal 116,675,981
With that explanation out of the way, let's continue. Next, we take the number 116,675,981 and divide it by 2:
116,675,981 ÷ 2 = 58,337,990.5
If the quotient is a whole number, then 2 and 58,337,990.5 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 | 116,675,981 | |
| -1 | -116,675,981 |
Now, we try dividing 116,675,981 by 3:
116,675,981 ÷ 3 = 38,891,993.6667
If the quotient is a whole number, then 3 and 38,891,993.6667 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 | 116,675,981 | |
| -1 | -116,675,981 |
Let's try dividing by 4:
116,675,981 ÷ 4 = 29,168,995.25
If the quotient is a whole number, then 4 and 29,168,995.25 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 | 116,675,981 | |
| -1 | 116,675,981 |
If you did it right, you will end up with this table:
| 1 | 17 | 59 | 61 | 1,003 | 1,037 | 1,907 | 3,599 | 32,419 | 61,183 | 112,513 | 116,327 | 1,912,721 | 1,977,559 | 6,863,293 | 116,675,981 |
| -1 | -17 | -59 | -61 | -1,003 | -1,037 | -1,907 | -3,599 | -32,419 | -61,183 | -112,513 | -116,327 | -1,912,721 | -1,977,559 | -6,863,293 | -116,675,981 |
