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 113,321,039, 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 | 113,321,039 | |
| -1 | -113,321,039 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,321,039.
Example:
1 x 113,321,039 = 113,321,039
and
-1 x -113,321,039 = 113,321,039
Notice both answers equal 113,321,039
With that explanation out of the way, let's continue. Next, we take the number 113,321,039 and divide it by 2:
113,321,039 ÷ 2 = 56,660,519.5
If the quotient is a whole number, then 2 and 56,660,519.5 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 | 113,321,039 | |
| -1 | -113,321,039 |
Now, we try dividing 113,321,039 by 3:
113,321,039 ÷ 3 = 37,773,679.6667
If the quotient is a whole number, then 3 and 37,773,679.6667 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 | 113,321,039 | |
| -1 | -113,321,039 |
Let's try dividing by 4:
113,321,039 ÷ 4 = 28,330,259.75
If the quotient is a whole number, then 4 and 28,330,259.75 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 | 113,321,039 | |
| -1 | 113,321,039 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 73 | 559 | 949 | 2,777 | 3,139 | 36,101 | 40,807 | 119,411 | 202,721 | 1,552,343 | 2,635,373 | 8,717,003 | 113,321,039 |
| -1 | -13 | -43 | -73 | -559 | -949 | -2,777 | -3,139 | -36,101 | -40,807 | -119,411 | -202,721 | -1,552,343 | -2,635,373 | -8,717,003 | -113,321,039 |
