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 122,036,045, 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 | 122,036,045 | |
| -1 | -122,036,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,036,045.
Example:
1 x 122,036,045 = 122,036,045
and
-1 x -122,036,045 = 122,036,045
Notice both answers equal 122,036,045
With that explanation out of the way, let's continue. Next, we take the number 122,036,045 and divide it by 2:
122,036,045 ÷ 2 = 61,018,022.5
If the quotient is a whole number, then 2 and 61,018,022.5 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 | 122,036,045 | |
| -1 | -122,036,045 |
Now, we try dividing 122,036,045 by 3:
122,036,045 ÷ 3 = 40,678,681.6667
If the quotient is a whole number, then 3 and 40,678,681.6667 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 | 122,036,045 | |
| -1 | -122,036,045 |
Let's try dividing by 4:
122,036,045 ÷ 4 = 30,509,011.25
If the quotient is a whole number, then 4 and 30,509,011.25 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 | 122,036,045 | |
| -1 | 122,036,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 113 | 115 | 565 | 2,599 | 9,391 | 12,995 | 46,955 | 215,993 | 1,061,183 | 1,079,965 | 5,305,915 | 24,407,209 | 122,036,045 |
| -1 | -5 | -23 | -113 | -115 | -565 | -2,599 | -9,391 | -12,995 | -46,955 | -215,993 | -1,061,183 | -1,079,965 | -5,305,915 | -24,407,209 | -122,036,045 |
