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 24,085,385, 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 | 24,085,385 | |
| -1 | -24,085,385 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,085,385.
Example:
1 x 24,085,385 = 24,085,385
and
-1 x -24,085,385 = 24,085,385
Notice both answers equal 24,085,385
With that explanation out of the way, let's continue. Next, we take the number 24,085,385 and divide it by 2:
24,085,385 ÷ 2 = 12,042,692.5
If the quotient is a whole number, then 2 and 12,042,692.5 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 | 24,085,385 | |
| -1 | -24,085,385 |
Now, we try dividing 24,085,385 by 3:
24,085,385 ÷ 3 = 8,028,461.6667
If the quotient is a whole number, then 3 and 8,028,461.6667 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 | 24,085,385 | |
| -1 | -24,085,385 |
Let's try dividing by 4:
24,085,385 ÷ 4 = 6,021,346.25
If the quotient is a whole number, then 4 and 6,021,346.25 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 | 24,085,385 | |
| -1 | 24,085,385 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 113 | 235 | 565 | 907 | 4,535 | 5,311 | 26,555 | 42,629 | 102,491 | 213,145 | 512,455 | 4,817,077 | 24,085,385 |
| -1 | -5 | -47 | -113 | -235 | -565 | -907 | -4,535 | -5,311 | -26,555 | -42,629 | -102,491 | -213,145 | -512,455 | -4,817,077 | -24,085,385 |
