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 612,065,233, 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 | 612,065,233 | |
| -1 | -612,065,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,065,233.
Example:
1 x 612,065,233 = 612,065,233
and
-1 x -612,065,233 = 612,065,233
Notice both answers equal 612,065,233
With that explanation out of the way, let's continue. Next, we take the number 612,065,233 and divide it by 2:
612,065,233 ÷ 2 = 306,032,616.5
If the quotient is a whole number, then 2 and 306,032,616.5 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 | 612,065,233 | |
| -1 | -612,065,233 |
Now, we try dividing 612,065,233 by 3:
612,065,233 ÷ 3 = 204,021,744.3333
If the quotient is a whole number, then 3 and 204,021,744.3333 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 | 612,065,233 | |
| -1 | -612,065,233 |
Let's try dividing by 4:
612,065,233 ÷ 4 = 153,016,308.25
If the quotient is a whole number, then 4 and 153,016,308.25 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 | 612,065,233 | |
| -1 | 612,065,233 |
If you did it right, you will end up with this table:
| 1 | 13 | 59 | 139 | 767 | 1,807 | 5,741 | 8,201 | 74,633 | 106,613 | 338,719 | 797,999 | 4,403,347 | 10,373,987 | 47,081,941 | 612,065,233 |
| -1 | -13 | -59 | -139 | -767 | -1,807 | -5,741 | -8,201 | -74,633 | -106,613 | -338,719 | -797,999 | -4,403,347 | -10,373,987 | -47,081,941 | -612,065,233 |
