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 30,065,257, 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 | 30,065,257 | |
| -1 | -30,065,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,065,257.
Example:
1 x 30,065,257 = 30,065,257
and
-1 x -30,065,257 = 30,065,257
Notice both answers equal 30,065,257
With that explanation out of the way, let's continue. Next, we take the number 30,065,257 and divide it by 2:
30,065,257 ÷ 2 = 15,032,628.5
If the quotient is a whole number, then 2 and 15,032,628.5 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 | 30,065,257 | |
| -1 | -30,065,257 |
Now, we try dividing 30,065,257 by 3:
30,065,257 ÷ 3 = 10,021,752.3333
If the quotient is a whole number, then 3 and 10,021,752.3333 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 | 30,065,257 | |
| -1 | -30,065,257 |
Let's try dividing by 4:
30,065,257 ÷ 4 = 7,516,314.25
If the quotient is a whole number, then 4 and 7,516,314.25 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 | 30,065,257 | |
| -1 | 30,065,257 |
If you did it right, you will end up with this table:
| 1 | 29 | 31 | 53 | 631 | 899 | 1,537 | 1,643 | 18,299 | 19,561 | 33,443 | 47,647 | 567,269 | 969,847 | 1,036,733 | 30,065,257 |
| -1 | -29 | -31 | -53 | -631 | -899 | -1,537 | -1,643 | -18,299 | -19,561 | -33,443 | -47,647 | -567,269 | -969,847 | -1,036,733 | -30,065,257 |
