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 125,423,365, 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 | 125,423,365 | |
| -1 | -125,423,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,423,365.
Example:
1 x 125,423,365 = 125,423,365
and
-1 x -125,423,365 = 125,423,365
Notice both answers equal 125,423,365
With that explanation out of the way, let's continue. Next, we take the number 125,423,365 and divide it by 2:
125,423,365 ÷ 2 = 62,711,682.5
If the quotient is a whole number, then 2 and 62,711,682.5 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 | 125,423,365 | |
| -1 | -125,423,365 |
Now, we try dividing 125,423,365 by 3:
125,423,365 ÷ 3 = 41,807,788.3333
If the quotient is a whole number, then 3 and 41,807,788.3333 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 | 125,423,365 | |
| -1 | -125,423,365 |
Let's try dividing by 4:
125,423,365 ÷ 4 = 31,355,841.25
If the quotient is a whole number, then 4 and 31,355,841.25 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 | 125,423,365 | |
| -1 | 125,423,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 31 | 85 | 155 | 527 | 2,635 | 47,599 | 237,995 | 809,183 | 1,475,569 | 4,045,915 | 7,377,845 | 25,084,673 | 125,423,365 |
| -1 | -5 | -17 | -31 | -85 | -155 | -527 | -2,635 | -47,599 | -237,995 | -809,183 | -1,475,569 | -4,045,915 | -7,377,845 | -25,084,673 | -125,423,365 |
