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 5,712,623, 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 | 5,712,623 | |
| -1 | -5,712,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,712,623.
Example:
1 x 5,712,623 = 5,712,623
and
-1 x -5,712,623 = 5,712,623
Notice both answers equal 5,712,623
With that explanation out of the way, let's continue. Next, we take the number 5,712,623 and divide it by 2:
5,712,623 ÷ 2 = 2,856,311.5
If the quotient is a whole number, then 2 and 2,856,311.5 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 | 5,712,623 | |
| -1 | -5,712,623 |
Now, we try dividing 5,712,623 by 3:
5,712,623 ÷ 3 = 1,904,207.6667
If the quotient is a whole number, then 3 and 1,904,207.6667 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 | 5,712,623 | |
| -1 | -5,712,623 |
Let's try dividing by 4:
5,712,623 ÷ 4 = 1,428,155.75
If the quotient is a whole number, then 4 and 1,428,155.75 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 | 5,712,623 | |
| -1 | 5,712,623 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 107 | 203 | 263 | 749 | 1,841 | 3,103 | 7,627 | 21,721 | 28,141 | 53,389 | 196,987 | 816,089 | 5,712,623 |
| -1 | -7 | -29 | -107 | -203 | -263 | -749 | -1,841 | -3,103 | -7,627 | -21,721 | -28,141 | -53,389 | -196,987 | -816,089 | -5,712,623 |
