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 112,022,009, 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 | 112,022,009 | |
| -1 | -112,022,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,022,009.
Example:
1 x 112,022,009 = 112,022,009
and
-1 x -112,022,009 = 112,022,009
Notice both answers equal 112,022,009
With that explanation out of the way, let's continue. Next, we take the number 112,022,009 and divide it by 2:
112,022,009 ÷ 2 = 56,011,004.5
If the quotient is a whole number, then 2 and 56,011,004.5 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 | 112,022,009 | |
| -1 | -112,022,009 |
Now, we try dividing 112,022,009 by 3:
112,022,009 ÷ 3 = 37,340,669.6667
If the quotient is a whole number, then 3 and 37,340,669.6667 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 | 112,022,009 | |
| -1 | -112,022,009 |
Let's try dividing by 4:
112,022,009 ÷ 4 = 28,005,502.25
If the quotient is a whole number, then 4 and 28,005,502.25 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 | 112,022,009 | |
| -1 | 112,022,009 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 47 | 473 | 517 | 2,021 | 5,039 | 22,231 | 55,429 | 216,677 | 236,833 | 2,383,447 | 2,605,163 | 10,183,819 | 112,022,009 |
| -1 | -11 | -43 | -47 | -473 | -517 | -2,021 | -5,039 | -22,231 | -55,429 | -216,677 | -236,833 | -2,383,447 | -2,605,163 | -10,183,819 | -112,022,009 |
