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 712,231,235, 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 | 712,231,235 | |
| -1 | -712,231,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 712,231,235.
Example:
1 x 712,231,235 = 712,231,235
and
-1 x -712,231,235 = 712,231,235
Notice both answers equal 712,231,235
With that explanation out of the way, let's continue. Next, we take the number 712,231,235 and divide it by 2:
712,231,235 ÷ 2 = 356,115,617.5
If the quotient is a whole number, then 2 and 356,115,617.5 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 | 712,231,235 | |
| -1 | -712,231,235 |
Now, we try dividing 712,231,235 by 3:
712,231,235 ÷ 3 = 237,410,411.6667
If the quotient is a whole number, then 3 and 237,410,411.6667 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 | 712,231,235 | |
| -1 | -712,231,235 |
Let's try dividing by 4:
712,231,235 ÷ 4 = 178,057,808.75
If the quotient is a whole number, then 4 and 178,057,808.75 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 | 712,231,235 | |
| -1 | 712,231,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 881 | 4,405 | 9,511 | 14,977 | 47,555 | 74,885 | 161,687 | 808,435 | 8,379,191 | 41,895,955 | 142,446,247 | 712,231,235 |
| -1 | -5 | -17 | -85 | -881 | -4,405 | -9,511 | -14,977 | -47,555 | -74,885 | -161,687 | -808,435 | -8,379,191 | -41,895,955 | -142,446,247 | -712,231,235 |
