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 25,703,575, 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 | 25,703,575 | |
| -1 | -25,703,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,703,575.
Example:
1 x 25,703,575 = 25,703,575
and
-1 x -25,703,575 = 25,703,575
Notice both answers equal 25,703,575
With that explanation out of the way, let's continue. Next, we take the number 25,703,575 and divide it by 2:
25,703,575 ÷ 2 = 12,851,787.5
If the quotient is a whole number, then 2 and 12,851,787.5 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 | 25,703,575 | |
| -1 | -25,703,575 |
Now, we try dividing 25,703,575 by 3:
25,703,575 ÷ 3 = 8,567,858.3333
If the quotient is a whole number, then 3 and 8,567,858.3333 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 | 25,703,575 | |
| -1 | -25,703,575 |
Let's try dividing by 4:
25,703,575 ÷ 4 = 6,425,893.75
If the quotient is a whole number, then 4 and 6,425,893.75 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 | 25,703,575 | |
| -1 | 25,703,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 197 | 307 | 425 | 985 | 1,535 | 3,349 | 4,925 | 5,219 | 7,675 | 16,745 | 26,095 | 60,479 | 83,725 | 130,475 | 302,395 | 1,028,143 | 1,511,975 | 5,140,715 | 25,703,575 |
| -1 | -5 | -17 | -25 | -85 | -197 | -307 | -425 | -985 | -1,535 | -3,349 | -4,925 | -5,219 | -7,675 | -16,745 | -26,095 | -60,479 | -83,725 | -130,475 | -302,395 | -1,028,143 | -1,511,975 | -5,140,715 | -25,703,575 |
