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 25,468,873, 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 | 25,468,873 | |
| -1 | -25,468,873 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,468,873.
Example:
1 x 25,468,873 = 25,468,873
and
-1 x -25,468,873 = 25,468,873
Notice both answers equal 25,468,873
With that explanation out of the way, let's continue. Next, we take the number 25,468,873 and divide it by 2:
25,468,873 ÷ 2 = 12,734,436.5
If the quotient is a whole number, then 2 and 12,734,436.5 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 | 25,468,873 | |
| -1 | -25,468,873 |
Now, we try dividing 25,468,873 by 3:
25,468,873 ÷ 3 = 8,489,624.3333
If the quotient is a whole number, then 3 and 8,489,624.3333 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 | 25,468,873 | |
| -1 | -25,468,873 |
Let's try dividing by 4:
25,468,873 ÷ 4 = 6,367,218.25
If the quotient is a whole number, then 4 and 6,367,218.25 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 | 25,468,873 | |
| -1 | 25,468,873 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 29 | 323 | 493 | 551 | 2,719 | 9,367 | 46,223 | 51,661 | 78,851 | 878,237 | 1,340,467 | 1,498,169 | 25,468,873 |
| -1 | -17 | -19 | -29 | -323 | -493 | -551 | -2,719 | -9,367 | -46,223 | -51,661 | -78,851 | -878,237 | -1,340,467 | -1,498,169 | -25,468,873 |
