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 25,405,303, 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 | 25,405,303 | |
| -1 | -25,405,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,405,303.
Example:
1 x 25,405,303 = 25,405,303
and
-1 x -25,405,303 = 25,405,303
Notice both answers equal 25,405,303
With that explanation out of the way, let's continue. Next, we take the number 25,405,303 and divide it by 2:
25,405,303 ÷ 2 = 12,702,651.5
If the quotient is a whole number, then 2 and 12,702,651.5 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 | 25,405,303 | |
| -1 | -25,405,303 |
Now, we try dividing 25,405,303 by 3:
25,405,303 ÷ 3 = 8,468,434.3333
If the quotient is a whole number, then 3 and 8,468,434.3333 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 | 25,405,303 | |
| -1 | -25,405,303 |
Let's try dividing by 4:
25,405,303 ÷ 4 = 6,351,325.75
If the quotient is a whole number, then 4 and 6,351,325.75 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 | 25,405,303 | |
| -1 | 25,405,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 43 | 77 | 301 | 473 | 3,311 | 7,673 | 53,711 | 84,403 | 329,939 | 590,821 | 2,309,573 | 3,629,329 | 25,405,303 |
| -1 | -7 | -11 | -43 | -77 | -301 | -473 | -3,311 | -7,673 | -53,711 | -84,403 | -329,939 | -590,821 | -2,309,573 | -3,629,329 | -25,405,303 |
