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 122,325,545, 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 | 122,325,545 | |
| -1 | -122,325,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,325,545.
Example:
1 x 122,325,545 = 122,325,545
and
-1 x -122,325,545 = 122,325,545
Notice both answers equal 122,325,545
With that explanation out of the way, let's continue. Next, we take the number 122,325,545 and divide it by 2:
122,325,545 ÷ 2 = 61,162,772.5
If the quotient is a whole number, then 2 and 61,162,772.5 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 | 122,325,545 | |
| -1 | -122,325,545 |
Now, we try dividing 122,325,545 by 3:
122,325,545 ÷ 3 = 40,775,181.6667
If the quotient is a whole number, then 3 and 40,775,181.6667 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 | 122,325,545 | |
| -1 | -122,325,545 |
Let's try dividing by 4:
122,325,545 ÷ 4 = 30,581,386.25
If the quotient is a whole number, then 4 and 30,581,386.25 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 | 122,325,545 | |
| -1 | 122,325,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 317 | 355 | 1,087 | 1,585 | 5,435 | 22,507 | 77,177 | 112,535 | 344,579 | 385,885 | 1,722,895 | 24,465,109 | 122,325,545 |
| -1 | -5 | -71 | -317 | -355 | -1,087 | -1,585 | -5,435 | -22,507 | -77,177 | -112,535 | -344,579 | -385,885 | -1,722,895 | -24,465,109 | -122,325,545 |
