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 125,542,535, 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 | 125,542,535 | |
| -1 | -125,542,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,542,535.
Example:
1 x 125,542,535 = 125,542,535
and
-1 x -125,542,535 = 125,542,535
Notice both answers equal 125,542,535
With that explanation out of the way, let's continue. Next, we take the number 125,542,535 and divide it by 2:
125,542,535 ÷ 2 = 62,771,267.5
If the quotient is a whole number, then 2 and 62,771,267.5 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 | 125,542,535 | |
| -1 | -125,542,535 |
Now, we try dividing 125,542,535 by 3:
125,542,535 ÷ 3 = 41,847,511.6667
If the quotient is a whole number, then 3 and 41,847,511.6667 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 | 125,542,535 | |
| -1 | -125,542,535 |
Let's try dividing by 4:
125,542,535 ÷ 4 = 31,385,633.75
If the quotient is a whole number, then 4 and 31,385,633.75 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 | 125,542,535 | |
| -1 | 125,542,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 643 | 2,297 | 3,215 | 10,931 | 11,485 | 39,049 | 54,655 | 195,245 | 1,476,971 | 7,384,855 | 25,108,507 | 125,542,535 |
| -1 | -5 | -17 | -85 | -643 | -2,297 | -3,215 | -10,931 | -11,485 | -39,049 | -54,655 | -195,245 | -1,476,971 | -7,384,855 | -25,108,507 | -125,542,535 |
