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 25,233,139, 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 | 25,233,139 | |
| -1 | -25,233,139 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,233,139.
Example:
1 x 25,233,139 = 25,233,139
and
-1 x -25,233,139 = 25,233,139
Notice both answers equal 25,233,139
With that explanation out of the way, let's continue. Next, we take the number 25,233,139 and divide it by 2:
25,233,139 ÷ 2 = 12,616,569.5
If the quotient is a whole number, then 2 and 12,616,569.5 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 | 25,233,139 | |
| -1 | -25,233,139 |
Now, we try dividing 25,233,139 by 3:
25,233,139 ÷ 3 = 8,411,046.3333
If the quotient is a whole number, then 3 and 8,411,046.3333 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 | 25,233,139 | |
| -1 | -25,233,139 |
Let's try dividing by 4:
25,233,139 ÷ 4 = 6,308,284.75
If the quotient is a whole number, then 4 and 6,308,284.75 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 | 25,233,139 | |
| -1 | 25,233,139 |
If you did it right, you will end up with this table:
| 1 | 23 | 197 | 4,531 | 5,569 | 128,087 | 1,097,093 | 25,233,139 |
| -1 | -23 | -197 | -4,531 | -5,569 | -128,087 | -1,097,093 | -25,233,139 |
