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 25,063,049, 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 | 25,063,049 | |
| -1 | -25,063,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,063,049.
Example:
1 x 25,063,049 = 25,063,049
and
-1 x -25,063,049 = 25,063,049
Notice both answers equal 25,063,049
With that explanation out of the way, let's continue. Next, we take the number 25,063,049 and divide it by 2:
25,063,049 ÷ 2 = 12,531,524.5
If the quotient is a whole number, then 2 and 12,531,524.5 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 | 25,063,049 | |
| -1 | -25,063,049 |
Now, we try dividing 25,063,049 by 3:
25,063,049 ÷ 3 = 8,354,349.6667
If the quotient is a whole number, then 3 and 8,354,349.6667 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 | 25,063,049 | |
| -1 | -25,063,049 |
Let's try dividing by 4:
25,063,049 ÷ 4 = 6,265,762.25
If the quotient is a whole number, then 4 and 6,265,762.25 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 | 25,063,049 | |
| -1 | 25,063,049 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 101 | 187 | 1,111 | 1,327 | 1,717 | 14,597 | 18,887 | 22,559 | 134,027 | 248,149 | 1,474,297 | 2,278,459 | 25,063,049 |
| -1 | -11 | -17 | -101 | -187 | -1,111 | -1,327 | -1,717 | -14,597 | -18,887 | -22,559 | -134,027 | -248,149 | -1,474,297 | -2,278,459 | -25,063,049 |
