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 125,113,043, 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 | 125,113,043 | |
| -1 | -125,113,043 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 125,113,043.
Example:
1 x 125,113,043 = 125,113,043
and
-1 x -125,113,043 = 125,113,043
Notice both answers equal 125,113,043
With that explanation out of the way, let's continue. Next, we take the number 125,113,043 and divide it by 2:
125,113,043 ÷ 2 = 62,556,521.5
If the quotient is a whole number, then 2 and 62,556,521.5 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 | 125,113,043 | |
| -1 | -125,113,043 |
Now, we try dividing 125,113,043 by 3:
125,113,043 ÷ 3 = 41,704,347.6667
If the quotient is a whole number, then 3 and 41,704,347.6667 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 | 125,113,043 | |
| -1 | -125,113,043 |
Let's try dividing by 4:
125,113,043 ÷ 4 = 31,278,260.75
If the quotient is a whole number, then 4 and 31,278,260.75 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 | 125,113,043 | |
| -1 | 125,113,043 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 101 | 209 | 1,111 | 1,919 | 5,927 | 21,109 | 65,197 | 112,613 | 598,627 | 1,238,743 | 6,584,897 | 11,373,913 | 125,113,043 |
| -1 | -11 | -19 | -101 | -209 | -1,111 | -1,919 | -5,927 | -21,109 | -65,197 | -112,613 | -598,627 | -1,238,743 | -6,584,897 | -11,373,913 | -125,113,043 |
