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 125,356,165, 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 | 125,356,165 | |
| -1 | -125,356,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,356,165.
Example:
1 x 125,356,165 = 125,356,165
and
-1 x -125,356,165 = 125,356,165
Notice both answers equal 125,356,165
With that explanation out of the way, let's continue. Next, we take the number 125,356,165 and divide it by 2:
125,356,165 ÷ 2 = 62,678,082.5
If the quotient is a whole number, then 2 and 62,678,082.5 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 | 125,356,165 | |
| -1 | -125,356,165 |
Now, we try dividing 125,356,165 by 3:
125,356,165 ÷ 3 = 41,785,388.3333
If the quotient is a whole number, then 3 and 41,785,388.3333 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 | 125,356,165 | |
| -1 | -125,356,165 |
Let's try dividing by 4:
125,356,165 ÷ 4 = 31,339,041.25
If the quotient is a whole number, then 4 and 31,339,041.25 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 | 125,356,165 | |
| -1 | 125,356,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 191 | 955 | 2,101 | 10,505 | 11,933 | 59,665 | 131,263 | 656,315 | 2,279,203 | 11,396,015 | 25,071,233 | 125,356,165 |
| -1 | -5 | -11 | -55 | -191 | -955 | -2,101 | -10,505 | -11,933 | -59,665 | -131,263 | -656,315 | -2,279,203 | -11,396,015 | -25,071,233 | -125,356,165 |
