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 125,172,467, 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 | 125,172,467 | |
| -1 | -125,172,467 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,172,467.
Example:
1 x 125,172,467 = 125,172,467
and
-1 x -125,172,467 = 125,172,467
Notice both answers equal 125,172,467
With that explanation out of the way, let's continue. Next, we take the number 125,172,467 and divide it by 2:
125,172,467 ÷ 2 = 62,586,233.5
If the quotient is a whole number, then 2 and 62,586,233.5 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 | 125,172,467 | |
| -1 | -125,172,467 |
Now, we try dividing 125,172,467 by 3:
125,172,467 ÷ 3 = 41,724,155.6667
If the quotient is a whole number, then 3 and 41,724,155.6667 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 | 125,172,467 | |
| -1 | -125,172,467 |
Let's try dividing by 4:
125,172,467 ÷ 4 = 31,293,116.75
If the quotient is a whole number, then 4 and 31,293,116.75 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 | 125,172,467 | |
| -1 | 125,172,467 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 287 | 587 | 743 | 4,109 | 5,201 | 24,067 | 30,463 | 168,469 | 213,241 | 436,141 | 3,052,987 | 17,881,781 | 125,172,467 |
| -1 | -7 | -41 | -287 | -587 | -743 | -4,109 | -5,201 | -24,067 | -30,463 | -168,469 | -213,241 | -436,141 | -3,052,987 | -17,881,781 | -125,172,467 |
