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 712,466,699, 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 | 712,466,699 | |
| -1 | -712,466,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,466,699.
Example:
1 x 712,466,699 = 712,466,699
and
-1 x -712,466,699 = 712,466,699
Notice both answers equal 712,466,699
With that explanation out of the way, let's continue. Next, we take the number 712,466,699 and divide it by 2:
712,466,699 ÷ 2 = 356,233,349.5
If the quotient is a whole number, then 2 and 356,233,349.5 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 | 712,466,699 | |
| -1 | -712,466,699 |
Now, we try dividing 712,466,699 by 3:
712,466,699 ÷ 3 = 237,488,899.6667
If the quotient is a whole number, then 3 and 237,488,899.6667 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 | 712,466,699 | |
| -1 | -712,466,699 |
Let's try dividing by 4:
712,466,699 ÷ 4 = 178,116,674.75
If the quotient is a whole number, then 4 and 178,116,674.75 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 | 712,466,699 | |
| -1 | 712,466,699 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 43 | 161 | 301 | 989 | 6,923 | 102,913 | 720,391 | 2,366,999 | 4,425,259 | 16,568,993 | 30,976,813 | 101,780,957 | 712,466,699 |
| -1 | -7 | -23 | -43 | -161 | -301 | -989 | -6,923 | -102,913 | -720,391 | -2,366,999 | -4,425,259 | -16,568,993 | -30,976,813 | -101,780,957 | -712,466,699 |
