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 723,613,177, 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 | 723,613,177 | |
| -1 | -723,613,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 723,613,177.
Example:
1 x 723,613,177 = 723,613,177
and
-1 x -723,613,177 = 723,613,177
Notice both answers equal 723,613,177
With that explanation out of the way, let's continue. Next, we take the number 723,613,177 and divide it by 2:
723,613,177 ÷ 2 = 361,806,588.5
If the quotient is a whole number, then 2 and 361,806,588.5 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 | 723,613,177 | |
| -1 | -723,613,177 |
Now, we try dividing 723,613,177 by 3:
723,613,177 ÷ 3 = 241,204,392.3333
If the quotient is a whole number, then 3 and 241,204,392.3333 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 | 723,613,177 | |
| -1 | -723,613,177 |
Let's try dividing by 4:
723,613,177 ÷ 4 = 180,903,294.25
If the quotient is a whole number, then 4 and 180,903,294.25 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 | 723,613,177 | |
| -1 | 723,613,177 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 109 | 119 | 763 | 1,853 | 12,971 | 55,787 | 390,509 | 948,379 | 6,080,783 | 6,638,653 | 42,565,481 | 103,373,311 | 723,613,177 |
| -1 | -7 | -17 | -109 | -119 | -763 | -1,853 | -12,971 | -55,787 | -390,509 | -948,379 | -6,080,783 | -6,638,653 | -42,565,481 | -103,373,311 | -723,613,177 |
