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 24,612,005, 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 | 24,612,005 | |
| -1 | -24,612,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,612,005.
Example:
1 x 24,612,005 = 24,612,005
and
-1 x -24,612,005 = 24,612,005
Notice both answers equal 24,612,005
With that explanation out of the way, let's continue. Next, we take the number 24,612,005 and divide it by 2:
24,612,005 ÷ 2 = 12,306,002.5
If the quotient is a whole number, then 2 and 12,306,002.5 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 | 24,612,005 | |
| -1 | -24,612,005 |
Now, we try dividing 24,612,005 by 3:
24,612,005 ÷ 3 = 8,204,001.6667
If the quotient is a whole number, then 3 and 8,204,001.6667 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 | 24,612,005 | |
| -1 | -24,612,005 |
Let's try dividing by 4:
24,612,005 ÷ 4 = 6,153,001.25
If the quotient is a whole number, then 4 and 6,153,001.25 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 | 24,612,005 | |
| -1 | 24,612,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 121 | 187 | 605 | 935 | 2,057 | 2,393 | 10,285 | 11,965 | 26,323 | 40,681 | 131,615 | 203,405 | 289,553 | 447,491 | 1,447,765 | 2,237,455 | 4,922,401 | 24,612,005 |
| -1 | -5 | -11 | -17 | -55 | -85 | -121 | -187 | -605 | -935 | -2,057 | -2,393 | -10,285 | -11,965 | -26,323 | -40,681 | -131,615 | -203,405 | -289,553 | -447,491 | -1,447,765 | -2,237,455 | -4,922,401 | -24,612,005 |
