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 25,004,399, 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 | 25,004,399 | |
| -1 | -25,004,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,004,399.
Example:
1 x 25,004,399 = 25,004,399
and
-1 x -25,004,399 = 25,004,399
Notice both answers equal 25,004,399
With that explanation out of the way, let's continue. Next, we take the number 25,004,399 and divide it by 2:
25,004,399 ÷ 2 = 12,502,199.5
If the quotient is a whole number, then 2 and 12,502,199.5 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 | 25,004,399 | |
| -1 | -25,004,399 |
Now, we try dividing 25,004,399 by 3:
25,004,399 ÷ 3 = 8,334,799.6667
If the quotient is a whole number, then 3 and 8,334,799.6667 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 | 25,004,399 | |
| -1 | -25,004,399 |
Let's try dividing by 4:
25,004,399 ÷ 4 = 6,251,099.75
If the quotient is a whole number, then 4 and 6,251,099.75 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 | 25,004,399 | |
| -1 | 25,004,399 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 119 | 133 | 323 | 2,261 | 11,059 | 77,413 | 188,003 | 210,121 | 1,316,021 | 1,470,847 | 3,572,057 | 25,004,399 |
| -1 | -7 | -17 | -19 | -119 | -133 | -323 | -2,261 | -11,059 | -77,413 | -188,003 | -210,121 | -1,316,021 | -1,470,847 | -3,572,057 | -25,004,399 |
