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 103,110,203, 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 | 103,110,203 | |
| -1 | -103,110,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,110,203.
Example:
1 x 103,110,203 = 103,110,203
and
-1 x -103,110,203 = 103,110,203
Notice both answers equal 103,110,203
With that explanation out of the way, let's continue. Next, we take the number 103,110,203 and divide it by 2:
103,110,203 ÷ 2 = 51,555,101.5
If the quotient is a whole number, then 2 and 51,555,101.5 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 | 103,110,203 | |
| -1 | -103,110,203 |
Now, we try dividing 103,110,203 by 3:
103,110,203 ÷ 3 = 34,370,067.6667
If the quotient is a whole number, then 3 and 34,370,067.6667 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 | 103,110,203 | |
| -1 | -103,110,203 |
Let's try dividing by 4:
103,110,203 ÷ 4 = 25,777,550.75
If the quotient is a whole number, then 4 and 25,777,550.75 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 | 103,110,203 | |
| -1 | 103,110,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 277 | 287 | 1,297 | 1,939 | 9,079 | 11,357 | 53,177 | 79,499 | 359,269 | 372,239 | 2,514,883 | 14,730,029 | 103,110,203 |
| -1 | -7 | -41 | -277 | -287 | -1,297 | -1,939 | -9,079 | -11,357 | -53,177 | -79,499 | -359,269 | -372,239 | -2,514,883 | -14,730,029 | -103,110,203 |
