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 50,702,203, 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 | 50,702,203 | |
| -1 | -50,702,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,702,203.
Example:
1 x 50,702,203 = 50,702,203
and
-1 x -50,702,203 = 50,702,203
Notice both answers equal 50,702,203
With that explanation out of the way, let's continue. Next, we take the number 50,702,203 and divide it by 2:
50,702,203 ÷ 2 = 25,351,101.5
If the quotient is a whole number, then 2 and 25,351,101.5 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 | 50,702,203 | |
| -1 | -50,702,203 |
Now, we try dividing 50,702,203 by 3:
50,702,203 ÷ 3 = 16,900,734.3333
If the quotient is a whole number, then 3 and 16,900,734.3333 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 | 50,702,203 | |
| -1 | -50,702,203 |
Let's try dividing by 4:
50,702,203 ÷ 4 = 12,675,550.75
If the quotient is a whole number, then 4 and 12,675,550.75 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 | 50,702,203 | |
| -1 | 50,702,203 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 229 | 271 | 817 | 4,351 | 5,149 | 9,847 | 11,653 | 62,059 | 187,093 | 221,407 | 1,179,121 | 2,668,537 | 50,702,203 |
| -1 | -19 | -43 | -229 | -271 | -817 | -4,351 | -5,149 | -9,847 | -11,653 | -62,059 | -187,093 | -221,407 | -1,179,121 | -2,668,537 | -50,702,203 |
