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 23,447,539, 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 | 23,447,539 | |
| -1 | -23,447,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,447,539.
Example:
1 x 23,447,539 = 23,447,539
and
-1 x -23,447,539 = 23,447,539
Notice both answers equal 23,447,539
With that explanation out of the way, let's continue. Next, we take the number 23,447,539 and divide it by 2:
23,447,539 ÷ 2 = 11,723,769.5
If the quotient is a whole number, then 2 and 11,723,769.5 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 | 23,447,539 | |
| -1 | -23,447,539 |
Now, we try dividing 23,447,539 by 3:
23,447,539 ÷ 3 = 7,815,846.3333
If the quotient is a whole number, then 3 and 7,815,846.3333 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 | 23,447,539 | |
| -1 | -23,447,539 |
Let's try dividing by 4:
23,447,539 ÷ 4 = 5,861,884.75
If the quotient is a whole number, then 4 and 5,861,884.75 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 | 23,447,539 | |
| -1 | 23,447,539 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 229 | 317 | 323 | 3,893 | 4,351 | 5,389 | 6,023 | 72,593 | 73,967 | 102,391 | 1,234,081 | 1,379,267 | 23,447,539 |
| -1 | -17 | -19 | -229 | -317 | -323 | -3,893 | -4,351 | -5,389 | -6,023 | -72,593 | -73,967 | -102,391 | -1,234,081 | -1,379,267 | -23,447,539 |
