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 122,525,545, 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 | 122,525,545 | |
| -1 | -122,525,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,525,545.
Example:
1 x 122,525,545 = 122,525,545
and
-1 x -122,525,545 = 122,525,545
Notice both answers equal 122,525,545
With that explanation out of the way, let's continue. Next, we take the number 122,525,545 and divide it by 2:
122,525,545 ÷ 2 = 61,262,772.5
If the quotient is a whole number, then 2 and 61,262,772.5 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 | 122,525,545 | |
| -1 | -122,525,545 |
Now, we try dividing 122,525,545 by 3:
122,525,545 ÷ 3 = 40,841,848.3333
If the quotient is a whole number, then 3 and 40,841,848.3333 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 | 122,525,545 | |
| -1 | -122,525,545 |
Let's try dividing by 4:
122,525,545 ÷ 4 = 30,631,386.25
If the quotient is a whole number, then 4 and 30,631,386.25 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 | 122,525,545 | |
| -1 | 122,525,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 191 | 955 | 3,247 | 7,547 | 16,235 | 37,735 | 128,299 | 641,495 | 1,441,477 | 7,207,385 | 24,505,109 | 122,525,545 |
| -1 | -5 | -17 | -85 | -191 | -955 | -3,247 | -7,547 | -16,235 | -37,735 | -128,299 | -641,495 | -1,441,477 | -7,207,385 | -24,505,109 | -122,525,545 |
