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 612,156,233, 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 | 612,156,233 | |
| -1 | -612,156,233 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,156,233.
Example:
1 x 612,156,233 = 612,156,233
and
-1 x -612,156,233 = 612,156,233
Notice both answers equal 612,156,233
With that explanation out of the way, let's continue. Next, we take the number 612,156,233 and divide it by 2:
612,156,233 ÷ 2 = 306,078,116.5
If the quotient is a whole number, then 2 and 306,078,116.5 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 | 612,156,233 | |
| -1 | -612,156,233 |
Now, we try dividing 612,156,233 by 3:
612,156,233 ÷ 3 = 204,052,077.6667
If the quotient is a whole number, then 3 and 204,052,077.6667 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 | 612,156,233 | |
| -1 | -612,156,233 |
Let's try dividing by 4:
612,156,233 ÷ 4 = 153,039,058.25
If the quotient is a whole number, then 4 and 153,039,058.25 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 | 612,156,233 | |
| -1 | 612,156,233 |
If you did it right, you will end up with this table:
| 1 | 13 | 97 | 347 | 1,261 | 1,399 | 4,511 | 18,187 | 33,659 | 135,703 | 437,567 | 485,453 | 1,764,139 | 6,310,889 | 47,088,941 | 612,156,233 |
| -1 | -13 | -97 | -347 | -1,261 | -1,399 | -4,511 | -18,187 | -33,659 | -135,703 | -437,567 | -485,453 | -1,764,139 | -6,310,889 | -47,088,941 | -612,156,233 |
