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 108,080,849, 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 | 108,080,849 | |
| -1 | -108,080,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,080,849.
Example:
1 x 108,080,849 = 108,080,849
and
-1 x -108,080,849 = 108,080,849
Notice both answers equal 108,080,849
With that explanation out of the way, let's continue. Next, we take the number 108,080,849 and divide it by 2:
108,080,849 ÷ 2 = 54,040,424.5
If the quotient is a whole number, then 2 and 54,040,424.5 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 | 108,080,849 | |
| -1 | -108,080,849 |
Now, we try dividing 108,080,849 by 3:
108,080,849 ÷ 3 = 36,026,949.6667
If the quotient is a whole number, then 3 and 36,026,949.6667 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 | 108,080,849 | |
| -1 | -108,080,849 |
Let's try dividing by 4:
108,080,849 ÷ 4 = 27,020,212.25
If the quotient is a whole number, then 4 and 27,020,212.25 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 | 108,080,849 | |
| -1 | 108,080,849 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 67 | 527 | 1,139 | 2,077 | 3,061 | 35,309 | 52,037 | 94,891 | 205,087 | 1,613,147 | 3,486,479 | 6,357,697 | 108,080,849 |
| -1 | -17 | -31 | -67 | -527 | -1,139 | -2,077 | -3,061 | -35,309 | -52,037 | -94,891 | -205,087 | -1,613,147 | -3,486,479 | -6,357,697 | -108,080,849 |
