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 24,504,403, 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 | 24,504,403 | |
| -1 | -24,504,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,504,403.
Example:
1 x 24,504,403 = 24,504,403
and
-1 x -24,504,403 = 24,504,403
Notice both answers equal 24,504,403
With that explanation out of the way, let's continue. Next, we take the number 24,504,403 and divide it by 2:
24,504,403 ÷ 2 = 12,252,201.5
If the quotient is a whole number, then 2 and 12,252,201.5 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 | 24,504,403 | |
| -1 | -24,504,403 |
Now, we try dividing 24,504,403 by 3:
24,504,403 ÷ 3 = 8,168,134.3333
If the quotient is a whole number, then 3 and 8,168,134.3333 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 | 24,504,403 | |
| -1 | -24,504,403 |
Let's try dividing by 4:
24,504,403 ÷ 4 = 6,126,100.75
If the quotient is a whole number, then 4 and 6,126,100.75 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 | 24,504,403 | |
| -1 | 24,504,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 157 | 1,099 | 1,727 | 2,027 | 12,089 | 14,189 | 22,297 | 156,079 | 318,239 | 2,227,673 | 3,500,629 | 24,504,403 |
| -1 | -7 | -11 | -77 | -157 | -1,099 | -1,727 | -2,027 | -12,089 | -14,189 | -22,297 | -156,079 | -318,239 | -2,227,673 | -3,500,629 | -24,504,403 |
