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 113,214,031, 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 | 113,214,031 | |
| -1 | -113,214,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,214,031.
Example:
1 x 113,214,031 = 113,214,031
and
-1 x -113,214,031 = 113,214,031
Notice both answers equal 113,214,031
With that explanation out of the way, let's continue. Next, we take the number 113,214,031 and divide it by 2:
113,214,031 ÷ 2 = 56,607,015.5
If the quotient is a whole number, then 2 and 56,607,015.5 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 | 113,214,031 | |
| -1 | -113,214,031 |
Now, we try dividing 113,214,031 by 3:
113,214,031 ÷ 3 = 37,738,010.3333
If the quotient is a whole number, then 3 and 37,738,010.3333 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 | 113,214,031 | |
| -1 | -113,214,031 |
Let's try dividing by 4:
113,214,031 ÷ 4 = 28,303,507.75
If the quotient is a whole number, then 4 and 28,303,507.75 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 | 113,214,031 | |
| -1 | 113,214,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 79 | 101 | 553 | 707 | 2,027 | 7,979 | 14,189 | 55,853 | 160,133 | 204,727 | 1,120,931 | 1,433,089 | 16,173,433 | 113,214,031 |
| -1 | -7 | -79 | -101 | -553 | -707 | -2,027 | -7,979 | -14,189 | -55,853 | -160,133 | -204,727 | -1,120,931 | -1,433,089 | -16,173,433 | -113,214,031 |
