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 24,750,811, 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 | 24,750,811 | |
| -1 | -24,750,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,750,811.
Example:
1 x 24,750,811 = 24,750,811
and
-1 x -24,750,811 = 24,750,811
Notice both answers equal 24,750,811
With that explanation out of the way, let's continue. Next, we take the number 24,750,811 and divide it by 2:
24,750,811 ÷ 2 = 12,375,405.5
If the quotient is a whole number, then 2 and 12,375,405.5 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 | 24,750,811 | |
| -1 | -24,750,811 |
Now, we try dividing 24,750,811 by 3:
24,750,811 ÷ 3 = 8,250,270.3333
If the quotient is a whole number, then 3 and 8,250,270.3333 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 | 24,750,811 | |
| -1 | -24,750,811 |
Let's try dividing by 4:
24,750,811 ÷ 4 = 6,187,702.75
If the quotient is a whole number, then 4 and 6,187,702.75 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 | 24,750,811 | |
| -1 | 24,750,811 |
If you did it right, you will end up with this table:
| 1 | 47 | 61 | 89 | 97 | 2,867 | 4,183 | 4,559 | 5,429 | 5,917 | 8,633 | 255,163 | 278,099 | 405,751 | 526,613 | 24,750,811 |
| -1 | -47 | -61 | -89 | -97 | -2,867 | -4,183 | -4,559 | -5,429 | -5,917 | -8,633 | -255,163 | -278,099 | -405,751 | -526,613 | -24,750,811 |
