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 125,530,223, 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 | 125,530,223 | |
| -1 | -125,530,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,530,223.
Example:
1 x 125,530,223 = 125,530,223
and
-1 x -125,530,223 = 125,530,223
Notice both answers equal 125,530,223
With that explanation out of the way, let's continue. Next, we take the number 125,530,223 and divide it by 2:
125,530,223 ÷ 2 = 62,765,111.5
If the quotient is a whole number, then 2 and 62,765,111.5 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 | 125,530,223 | |
| -1 | -125,530,223 |
Now, we try dividing 125,530,223 by 3:
125,530,223 ÷ 3 = 41,843,407.6667
If the quotient is a whole number, then 3 and 41,843,407.6667 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 | 125,530,223 | |
| -1 | -125,530,223 |
Let's try dividing by 4:
125,530,223 ÷ 4 = 31,382,555.75
If the quotient is a whole number, then 4 and 31,382,555.75 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 | 125,530,223 | |
| -1 | 125,530,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 137 | 959 | 1,781 | 10,069 | 12,467 | 70,483 | 130,897 | 916,279 | 1,379,453 | 9,656,171 | 17,932,889 | 125,530,223 |
| -1 | -7 | -13 | -91 | -137 | -959 | -1,781 | -10,069 | -12,467 | -70,483 | -130,897 | -916,279 | -1,379,453 | -9,656,171 | -17,932,889 | -125,530,223 |
