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 23,510,045, 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 | 23,510,045 | |
| -1 | -23,510,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,510,045.
Example:
1 x 23,510,045 = 23,510,045
and
-1 x -23,510,045 = 23,510,045
Notice both answers equal 23,510,045
With that explanation out of the way, let's continue. Next, we take the number 23,510,045 and divide it by 2:
23,510,045 ÷ 2 = 11,755,022.5
If the quotient is a whole number, then 2 and 11,755,022.5 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 | 23,510,045 | |
| -1 | -23,510,045 |
Now, we try dividing 23,510,045 by 3:
23,510,045 ÷ 3 = 7,836,681.6667
If the quotient is a whole number, then 3 and 7,836,681.6667 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 | 23,510,045 | |
| -1 | -23,510,045 |
Let's try dividing by 4:
23,510,045 ÷ 4 = 5,877,511.25
If the quotient is a whole number, then 4 and 5,877,511.25 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 | 23,510,045 | |
| -1 | 23,510,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 311 | 1,163 | 1,555 | 4,043 | 5,815 | 15,119 | 20,215 | 75,595 | 361,693 | 1,808,465 | 4,702,009 | 23,510,045 |
| -1 | -5 | -13 | -65 | -311 | -1,163 | -1,555 | -4,043 | -5,815 | -15,119 | -20,215 | -75,595 | -361,693 | -1,808,465 | -4,702,009 | -23,510,045 |
