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 30,751,253, 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 | 30,751,253 | |
| -1 | -30,751,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,751,253.
Example:
1 x 30,751,253 = 30,751,253
and
-1 x -30,751,253 = 30,751,253
Notice both answers equal 30,751,253
With that explanation out of the way, let's continue. Next, we take the number 30,751,253 and divide it by 2:
30,751,253 ÷ 2 = 15,375,626.5
If the quotient is a whole number, then 2 and 15,375,626.5 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 | 30,751,253 | |
| -1 | -30,751,253 |
Now, we try dividing 30,751,253 by 3:
30,751,253 ÷ 3 = 10,250,417.6667
If the quotient is a whole number, then 3 and 10,250,417.6667 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 | 30,751,253 | |
| -1 | -30,751,253 |
Let's try dividing by 4:
30,751,253 ÷ 4 = 7,687,813.25
If the quotient is a whole number, then 4 and 7,687,813.25 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 | 30,751,253 | |
| -1 | 30,751,253 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 23 | 247 | 299 | 437 | 5,413 | 5,681 | 70,369 | 102,847 | 124,499 | 1,337,011 | 1,618,487 | 2,365,481 | 30,751,253 |
| -1 | -13 | -19 | -23 | -247 | -299 | -437 | -5,413 | -5,681 | -70,369 | -102,847 | -124,499 | -1,337,011 | -1,618,487 | -2,365,481 | -30,751,253 |
