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 25,536,133, 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 | 25,536,133 | |
| -1 | -25,536,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 25,536,133.
Example:
1 x 25,536,133 = 25,536,133
and
-1 x -25,536,133 = 25,536,133
Notice both answers equal 25,536,133
With that explanation out of the way, let's continue. Next, we take the number 25,536,133 and divide it by 2:
25,536,133 ÷ 2 = 12,768,066.5
If the quotient is a whole number, then 2 and 12,768,066.5 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 | 25,536,133 | |
| -1 | -25,536,133 |
Now, we try dividing 25,536,133 by 3:
25,536,133 ÷ 3 = 8,512,044.3333
If the quotient is a whole number, then 3 and 8,512,044.3333 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 | 25,536,133 | |
| -1 | -25,536,133 |
Let's try dividing by 4:
25,536,133 ÷ 4 = 6,384,033.25
If the quotient is a whole number, then 4 and 6,384,033.25 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 | 25,536,133 | |
| -1 | 25,536,133 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 101 | 133 | 707 | 1,901 | 1,919 | 13,307 | 13,433 | 36,119 | 192,001 | 252,833 | 1,344,007 | 3,648,019 | 25,536,133 |
| -1 | -7 | -19 | -101 | -133 | -707 | -1,901 | -1,919 | -13,307 | -13,433 | -36,119 | -192,001 | -252,833 | -1,344,007 | -3,648,019 | -25,536,133 |
