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 24,540,005, 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 | 24,540,005 | |
| -1 | -24,540,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,540,005.
Example:
1 x 24,540,005 = 24,540,005
and
-1 x -24,540,005 = 24,540,005
Notice both answers equal 24,540,005
With that explanation out of the way, let's continue. Next, we take the number 24,540,005 and divide it by 2:
24,540,005 ÷ 2 = 12,270,002.5
If the quotient is a whole number, then 2 and 12,270,002.5 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 | 24,540,005 | |
| -1 | -24,540,005 |
Now, we try dividing 24,540,005 by 3:
24,540,005 ÷ 3 = 8,180,001.6667
If the quotient is a whole number, then 3 and 8,180,001.6667 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 | 24,540,005 | |
| -1 | -24,540,005 |
Let's try dividing by 4:
24,540,005 ÷ 4 = 6,135,001.25
If the quotient is a whole number, then 4 and 6,135,001.25 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 | 24,540,005 | |
| -1 | 24,540,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 179 | 895 | 1,253 | 3,917 | 6,265 | 19,585 | 27,419 | 137,095 | 701,143 | 3,505,715 | 4,908,001 | 24,540,005 |
| -1 | -5 | -7 | -35 | -179 | -895 | -1,253 | -3,917 | -6,265 | -19,585 | -27,419 | -137,095 | -701,143 | -3,505,715 | -4,908,001 | -24,540,005 |
