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 23,927,567, 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 | 23,927,567 | |
| -1 | -23,927,567 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,927,567.
Example:
1 x 23,927,567 = 23,927,567
and
-1 x -23,927,567 = 23,927,567
Notice both answers equal 23,927,567
With that explanation out of the way, let's continue. Next, we take the number 23,927,567 and divide it by 2:
23,927,567 ÷ 2 = 11,963,783.5
If the quotient is a whole number, then 2 and 11,963,783.5 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 | 23,927,567 | |
| -1 | -23,927,567 |
Now, we try dividing 23,927,567 by 3:
23,927,567 ÷ 3 = 7,975,855.6667
If the quotient is a whole number, then 3 and 7,975,855.6667 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 | 23,927,567 | |
| -1 | -23,927,567 |
Let's try dividing by 4:
23,927,567 ÷ 4 = 5,981,891.75
If the quotient is a whole number, then 4 and 5,981,891.75 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 | 23,927,567 | |
| -1 | 23,927,567 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 37 | 713 | 851 | 907 | 1,147 | 20,861 | 26,381 | 28,117 | 33,559 | 646,691 | 771,857 | 1,040,329 | 23,927,567 |
| -1 | -23 | -31 | -37 | -713 | -851 | -907 | -1,147 | -20,861 | -26,381 | -28,117 | -33,559 | -646,691 | -771,857 | -1,040,329 | -23,927,567 |
