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 24,535,885, 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 | 24,535,885 | |
| -1 | -24,535,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,535,885.
Example:
1 x 24,535,885 = 24,535,885
and
-1 x -24,535,885 = 24,535,885
Notice both answers equal 24,535,885
With that explanation out of the way, let's continue. Next, we take the number 24,535,885 and divide it by 2:
24,535,885 ÷ 2 = 12,267,942.5
If the quotient is a whole number, then 2 and 12,267,942.5 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 | 24,535,885 | |
| -1 | -24,535,885 |
Now, we try dividing 24,535,885 by 3:
24,535,885 ÷ 3 = 8,178,628.3333
If the quotient is a whole number, then 3 and 8,178,628.3333 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 | 24,535,885 | |
| -1 | -24,535,885 |
Let's try dividing by 4:
24,535,885 ÷ 4 = 6,133,971.25
If the quotient is a whole number, then 4 and 6,133,971.25 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 | 24,535,885 | |
| -1 | 24,535,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 15,383 | 76,915 | 169,213 | 446,107 | 846,065 | 2,230,535 | 4,907,177 | 24,535,885 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -15,383 | -76,915 | -169,213 | -446,107 | -846,065 | -2,230,535 | -4,907,177 | -24,535,885 |
