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 125,355,655, 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 | 125,355,655 | |
| -1 | -125,355,655 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,355,655.
Example:
1 x 125,355,655 = 125,355,655
and
-1 x -125,355,655 = 125,355,655
Notice both answers equal 125,355,655
With that explanation out of the way, let's continue. Next, we take the number 125,355,655 and divide it by 2:
125,355,655 ÷ 2 = 62,677,827.5
If the quotient is a whole number, then 2 and 62,677,827.5 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 | 125,355,655 | |
| -1 | -125,355,655 |
Now, we try dividing 125,355,655 by 3:
125,355,655 ÷ 3 = 41,785,218.3333
If the quotient is a whole number, then 3 and 41,785,218.3333 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 | 125,355,655 | |
| -1 | -125,355,655 |
Let's try dividing by 4:
125,355,655 ÷ 4 = 31,338,913.75
If the quotient is a whole number, then 4 and 31,338,913.75 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 | 125,355,655 | |
| -1 | 125,355,655 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 293 | 1,465 | 2,087 | 10,435 | 12,013 | 60,065 | 85,567 | 427,835 | 611,491 | 3,057,455 | 25,071,131 | 125,355,655 |
| -1 | -5 | -41 | -205 | -293 | -1,465 | -2,087 | -10,435 | -12,013 | -60,065 | -85,567 | -427,835 | -611,491 | -3,057,455 | -25,071,131 | -125,355,655 |
