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 125,015,033, 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 | 125,015,033 | |
| -1 | -125,015,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,015,033.
Example:
1 x 125,015,033 = 125,015,033
and
-1 x -125,015,033 = 125,015,033
Notice both answers equal 125,015,033
With that explanation out of the way, let's continue. Next, we take the number 125,015,033 and divide it by 2:
125,015,033 ÷ 2 = 62,507,516.5
If the quotient is a whole number, then 2 and 62,507,516.5 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 | 125,015,033 | |
| -1 | -125,015,033 |
Now, we try dividing 125,015,033 by 3:
125,015,033 ÷ 3 = 41,671,677.6667
If the quotient is a whole number, then 3 and 41,671,677.6667 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 | 125,015,033 | |
| -1 | -125,015,033 |
Let's try dividing by 4:
125,015,033 ÷ 4 = 31,253,758.25
If the quotient is a whole number, then 4 and 31,253,758.25 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 | 125,015,033 | |
| -1 | 125,015,033 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 341 | 403 | 4,433 | 28,201 | 310,211 | 366,613 | 874,231 | 4,032,743 | 9,616,541 | 11,365,003 | 125,015,033 |
| -1 | -11 | -13 | -31 | -143 | -341 | -403 | -4,433 | -28,201 | -310,211 | -366,613 | -874,231 | -4,032,743 | -9,616,541 | -11,365,003 | -125,015,033 |
