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 25,230,839, 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 | 25,230,839 | |
| -1 | -25,230,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,230,839.
Example:
1 x 25,230,839 = 25,230,839
and
-1 x -25,230,839 = 25,230,839
Notice both answers equal 25,230,839
With that explanation out of the way, let's continue. Next, we take the number 25,230,839 and divide it by 2:
25,230,839 ÷ 2 = 12,615,419.5
If the quotient is a whole number, then 2 and 12,615,419.5 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 | 25,230,839 | |
| -1 | -25,230,839 |
Now, we try dividing 25,230,839 by 3:
25,230,839 ÷ 3 = 8,410,279.6667
If the quotient is a whole number, then 3 and 8,410,279.6667 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 | 25,230,839 | |
| -1 | -25,230,839 |
Let's try dividing by 4:
25,230,839 ÷ 4 = 6,307,709.75
If the quotient is a whole number, then 4 and 6,307,709.75 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 | 25,230,839 | |
| -1 | 25,230,839 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 173 | 373 | 391 | 2,941 | 3,979 | 6,341 | 8,579 | 64,529 | 67,643 | 145,843 | 1,096,993 | 1,484,167 | 25,230,839 |
| -1 | -17 | -23 | -173 | -373 | -391 | -2,941 | -3,979 | -6,341 | -8,579 | -64,529 | -67,643 | -145,843 | -1,096,993 | -1,484,167 | -25,230,839 |
