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 23,512,511, 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 | 23,512,511 | |
| -1 | -23,512,511 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,512,511.
Example:
1 x 23,512,511 = 23,512,511
and
-1 x -23,512,511 = 23,512,511
Notice both answers equal 23,512,511
With that explanation out of the way, let's continue. Next, we take the number 23,512,511 and divide it by 2:
23,512,511 ÷ 2 = 11,756,255.5
If the quotient is a whole number, then 2 and 11,756,255.5 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 | 23,512,511 | |
| -1 | -23,512,511 |
Now, we try dividing 23,512,511 by 3:
23,512,511 ÷ 3 = 7,837,503.6667
If the quotient is a whole number, then 3 and 7,837,503.6667 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 | 23,512,511 | |
| -1 | -23,512,511 |
Let's try dividing by 4:
23,512,511 ÷ 4 = 5,878,127.75
If the quotient is a whole number, then 4 and 5,878,127.75 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 | 23,512,511 | |
| -1 | 23,512,511 |
If you did it right, you will end up with this table:
| 1 | 11 | 61 | 67 | 523 | 671 | 737 | 4,087 | 5,753 | 31,903 | 35,041 | 44,957 | 350,933 | 385,451 | 2,137,501 | 23,512,511 |
| -1 | -11 | -61 | -67 | -523 | -671 | -737 | -4,087 | -5,753 | -31,903 | -35,041 | -44,957 | -350,933 | -385,451 | -2,137,501 | -23,512,511 |
