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 25,010,383, 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 | 25,010,383 | |
| -1 | -25,010,383 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,010,383.
Example:
1 x 25,010,383 = 25,010,383
and
-1 x -25,010,383 = 25,010,383
Notice both answers equal 25,010,383
With that explanation out of the way, let's continue. Next, we take the number 25,010,383 and divide it by 2:
25,010,383 ÷ 2 = 12,505,191.5
If the quotient is a whole number, then 2 and 12,505,191.5 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 | 25,010,383 | |
| -1 | -25,010,383 |
Now, we try dividing 25,010,383 by 3:
25,010,383 ÷ 3 = 8,336,794.3333
If the quotient is a whole number, then 3 and 8,336,794.3333 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 | 25,010,383 | |
| -1 | -25,010,383 |
Let's try dividing by 4:
25,010,383 ÷ 4 = 6,252,595.75
If the quotient is a whole number, then 4 and 6,252,595.75 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 | 25,010,383 | |
| -1 | 25,010,383 |
If you did it right, you will end up with this table:
| 1 | 17 | 29 | 97 | 493 | 523 | 1,649 | 2,813 | 8,891 | 15,167 | 47,821 | 50,731 | 257,839 | 862,427 | 1,471,199 | 25,010,383 |
| -1 | -17 | -29 | -97 | -493 | -523 | -1,649 | -2,813 | -8,891 | -15,167 | -47,821 | -50,731 | -257,839 | -862,427 | -1,471,199 | -25,010,383 |
