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 122,003,203, 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 | 122,003,203 | |
| -1 | -122,003,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 122,003,203.
Example:
1 x 122,003,203 = 122,003,203
and
-1 x -122,003,203 = 122,003,203
Notice both answers equal 122,003,203
With that explanation out of the way, let's continue. Next, we take the number 122,003,203 and divide it by 2:
122,003,203 ÷ 2 = 61,001,601.5
If the quotient is a whole number, then 2 and 61,001,601.5 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 | 122,003,203 | |
| -1 | -122,003,203 |
Now, we try dividing 122,003,203 by 3:
122,003,203 ÷ 3 = 40,667,734.3333
If the quotient is a whole number, then 3 and 40,667,734.3333 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 | 122,003,203 | |
| -1 | -122,003,203 |
Let's try dividing by 4:
122,003,203 ÷ 4 = 30,500,800.75
If the quotient is a whole number, then 4 and 30,500,800.75 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 | 122,003,203 | |
| -1 | 122,003,203 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 29 | 119 | 203 | 493 | 3,451 | 35,353 | 247,471 | 601,001 | 1,025,237 | 4,207,007 | 7,176,659 | 17,429,029 | 122,003,203 |
| -1 | -7 | -17 | -29 | -119 | -203 | -493 | -3,451 | -35,353 | -247,471 | -601,001 | -1,025,237 | -4,207,007 | -7,176,659 | -17,429,029 | -122,003,203 |
