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 612,115,115, 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 | 612,115,115 | |
| -1 | -612,115,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,115,115.
Example:
1 x 612,115,115 = 612,115,115
and
-1 x -612,115,115 = 612,115,115
Notice both answers equal 612,115,115
With that explanation out of the way, let's continue. Next, we take the number 612,115,115 and divide it by 2:
612,115,115 ÷ 2 = 306,057,557.5
If the quotient is a whole number, then 2 and 306,057,557.5 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 | 612,115,115 | |
| -1 | -612,115,115 |
Now, we try dividing 612,115,115 by 3:
612,115,115 ÷ 3 = 204,038,371.6667
If the quotient is a whole number, then 3 and 204,038,371.6667 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 | 612,115,115 | |
| -1 | -612,115,115 |
Let's try dividing by 4:
612,115,115 ÷ 4 = 153,028,778.75
If the quotient is a whole number, then 4 and 153,028,778.75 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 | 612,115,115 | |
| -1 | 612,115,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 109 | 545 | 2,071 | 10,355 | 59,113 | 295,565 | 1,123,147 | 5,615,735 | 6,443,317 | 32,216,585 | 122,423,023 | 612,115,115 |
| -1 | -5 | -19 | -95 | -109 | -545 | -2,071 | -10,355 | -59,113 | -295,565 | -1,123,147 | -5,615,735 | -6,443,317 | -32,216,585 | -122,423,023 | -612,115,115 |
