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 50,172,703, 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 | 50,172,703 | |
| -1 | -50,172,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,172,703.
Example:
1 x 50,172,703 = 50,172,703
and
-1 x -50,172,703 = 50,172,703
Notice both answers equal 50,172,703
With that explanation out of the way, let's continue. Next, we take the number 50,172,703 and divide it by 2:
50,172,703 ÷ 2 = 25,086,351.5
If the quotient is a whole number, then 2 and 25,086,351.5 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 | 50,172,703 | |
| -1 | -50,172,703 |
Now, we try dividing 50,172,703 by 3:
50,172,703 ÷ 3 = 16,724,234.3333
If the quotient is a whole number, then 3 and 16,724,234.3333 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 | 50,172,703 | |
| -1 | -50,172,703 |
Let's try dividing by 4:
50,172,703 ÷ 4 = 12,543,175.75
If the quotient is a whole number, then 4 and 12,543,175.75 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 | 50,172,703 | |
| -1 | 50,172,703 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 307 | 631 | 2,149 | 4,417 | 11,359 | 23,347 | 79,513 | 163,429 | 193,717 | 1,356,019 | 7,167,529 | 50,172,703 |
| -1 | -7 | -37 | -259 | -307 | -631 | -2,149 | -4,417 | -11,359 | -23,347 | -79,513 | -163,429 | -193,717 | -1,356,019 | -7,167,529 | -50,172,703 |
