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 712,615,049, 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 | 712,615,049 | |
| -1 | -712,615,049 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,615,049.
Example:
1 x 712,615,049 = 712,615,049
and
-1 x -712,615,049 = 712,615,049
Notice both answers equal 712,615,049
With that explanation out of the way, let's continue. Next, we take the number 712,615,049 and divide it by 2:
712,615,049 ÷ 2 = 356,307,524.5
If the quotient is a whole number, then 2 and 356,307,524.5 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 | 712,615,049 | |
| -1 | -712,615,049 |
Now, we try dividing 712,615,049 by 3:
712,615,049 ÷ 3 = 237,538,349.6667
If the quotient is a whole number, then 3 and 237,538,349.6667 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 | 712,615,049 | |
| -1 | -712,615,049 |
Let's try dividing by 4:
712,615,049 ÷ 4 = 178,153,762.25
If the quotient is a whole number, then 4 and 178,153,762.25 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 | 712,615,049 | |
| -1 | 712,615,049 |
If you did it right, you will end up with this table:
| 1 | 23 | 43 | 317 | 989 | 2,273 | 7,291 | 13,631 | 52,279 | 97,739 | 313,513 | 720,541 | 2,247,997 | 16,572,443 | 30,983,263 | 712,615,049 |
| -1 | -23 | -43 | -317 | -989 | -2,273 | -7,291 | -13,631 | -52,279 | -97,739 | -313,513 | -720,541 | -2,247,997 | -16,572,443 | -30,983,263 | -712,615,049 |
