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 24,885,079, 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 | 24,885,079 | |
| -1 | -24,885,079 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,885,079.
Example:
1 x 24,885,079 = 24,885,079
and
-1 x -24,885,079 = 24,885,079
Notice both answers equal 24,885,079
With that explanation out of the way, let's continue. Next, we take the number 24,885,079 and divide it by 2:
24,885,079 ÷ 2 = 12,442,539.5
If the quotient is a whole number, then 2 and 12,442,539.5 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 | 24,885,079 | |
| -1 | -24,885,079 |
Now, we try dividing 24,885,079 by 3:
24,885,079 ÷ 3 = 8,295,026.3333
If the quotient is a whole number, then 3 and 8,295,026.3333 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 | 24,885,079 | |
| -1 | -24,885,079 |
Let's try dividing by 4:
24,885,079 ÷ 4 = 6,221,269.75
If the quotient is a whole number, then 4 and 6,221,269.75 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 | 24,885,079 | |
| -1 | 24,885,079 |
If you did it right, you will end up with this table:
| 1 | 19 | 59 | 79 | 281 | 1,121 | 1,501 | 4,661 | 5,339 | 16,579 | 22,199 | 88,559 | 315,001 | 421,781 | 1,309,741 | 24,885,079 |
| -1 | -19 | -59 | -79 | -281 | -1,121 | -1,501 | -4,661 | -5,339 | -16,579 | -22,199 | -88,559 | -315,001 | -421,781 | -1,309,741 | -24,885,079 |
