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 23,551,505, 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 | 23,551,505 | |
| -1 | -23,551,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,551,505.
Example:
1 x 23,551,505 = 23,551,505
and
-1 x -23,551,505 = 23,551,505
Notice both answers equal 23,551,505
With that explanation out of the way, let's continue. Next, we take the number 23,551,505 and divide it by 2:
23,551,505 ÷ 2 = 11,775,752.5
If the quotient is a whole number, then 2 and 11,775,752.5 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 | 23,551,505 | |
| -1 | -23,551,505 |
Now, we try dividing 23,551,505 by 3:
23,551,505 ÷ 3 = 7,850,501.6667
If the quotient is a whole number, then 3 and 7,850,501.6667 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 | 23,551,505 | |
| -1 | -23,551,505 |
Let's try dividing by 4:
23,551,505 ÷ 4 = 5,887,876.25
If the quotient is a whole number, then 4 and 5,887,876.25 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 | 23,551,505 | |
| -1 | 23,551,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 67 | 229 | 307 | 335 | 1,145 | 1,535 | 15,343 | 20,569 | 70,303 | 76,715 | 102,845 | 351,515 | 4,710,301 | 23,551,505 |
| -1 | -5 | -67 | -229 | -307 | -335 | -1,145 | -1,535 | -15,343 | -20,569 | -70,303 | -76,715 | -102,845 | -351,515 | -4,710,301 | -23,551,505 |
