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 24,666,313, 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 | 24,666,313 | |
| -1 | -24,666,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,666,313.
Example:
1 x 24,666,313 = 24,666,313
and
-1 x -24,666,313 = 24,666,313
Notice both answers equal 24,666,313
With that explanation out of the way, let's continue. Next, we take the number 24,666,313 and divide it by 2:
24,666,313 ÷ 2 = 12,333,156.5
If the quotient is a whole number, then 2 and 12,333,156.5 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 | 24,666,313 | |
| -1 | -24,666,313 |
Now, we try dividing 24,666,313 by 3:
24,666,313 ÷ 3 = 8,222,104.3333
If the quotient is a whole number, then 3 and 8,222,104.3333 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 | 24,666,313 | |
| -1 | -24,666,313 |
Let's try dividing by 4:
24,666,313 ÷ 4 = 6,166,578.25
If the quotient is a whole number, then 4 and 6,166,578.25 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 | 24,666,313 | |
| -1 | 24,666,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 191 | 971 | 1,337 | 3,629 | 6,797 | 18,449 | 25,403 | 129,143 | 185,461 | 1,298,227 | 3,523,759 | 24,666,313 |
| -1 | -7 | -19 | -133 | -191 | -971 | -1,337 | -3,629 | -6,797 | -18,449 | -25,403 | -129,143 | -185,461 | -1,298,227 | -3,523,759 | -24,666,313 |
