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 125,314,405, 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 | 125,314,405 | |
| -1 | -125,314,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,314,405.
Example:
1 x 125,314,405 = 125,314,405
and
-1 x -125,314,405 = 125,314,405
Notice both answers equal 125,314,405
With that explanation out of the way, let's continue. Next, we take the number 125,314,405 and divide it by 2:
125,314,405 ÷ 2 = 62,657,202.5
If the quotient is a whole number, then 2 and 62,657,202.5 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 | 125,314,405 | |
| -1 | -125,314,405 |
Now, we try dividing 125,314,405 by 3:
125,314,405 ÷ 3 = 41,771,468.3333
If the quotient is a whole number, then 3 and 41,771,468.3333 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 | 125,314,405 | |
| -1 | -125,314,405 |
Let's try dividing by 4:
125,314,405 ÷ 4 = 31,328,601.25
If the quotient is a whole number, then 4 and 31,328,601.25 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 | 125,314,405 | |
| -1 | 125,314,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 389 | 1,945 | 3,391 | 7,391 | 16,955 | 36,955 | 64,429 | 322,145 | 1,319,099 | 6,595,495 | 25,062,881 | 125,314,405 |
| -1 | -5 | -19 | -95 | -389 | -1,945 | -3,391 | -7,391 | -16,955 | -36,955 | -64,429 | -322,145 | -1,319,099 | -6,595,495 | -25,062,881 | -125,314,405 |
