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 612,066,235, 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 | 612,066,235 | |
| -1 | -612,066,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 612,066,235.
Example:
1 x 612,066,235 = 612,066,235
and
-1 x -612,066,235 = 612,066,235
Notice both answers equal 612,066,235
With that explanation out of the way, let's continue. Next, we take the number 612,066,235 and divide it by 2:
612,066,235 ÷ 2 = 306,033,117.5
If the quotient is a whole number, then 2 and 306,033,117.5 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 | 612,066,235 | |
| -1 | -612,066,235 |
Now, we try dividing 612,066,235 by 3:
612,066,235 ÷ 3 = 204,022,078.3333
If the quotient is a whole number, then 3 and 204,022,078.3333 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 | 612,066,235 | |
| -1 | -612,066,235 |
Let's try dividing by 4:
612,066,235 ÷ 4 = 153,016,558.75
If the quotient is a whole number, then 4 and 153,016,558.75 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 | 612,066,235 | |
| -1 | 612,066,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 2,707 | 4,111 | 13,535 | 20,555 | 29,777 | 45,221 | 148,885 | 226,105 | 11,128,477 | 55,642,385 | 122,413,247 | 612,066,235 |
| -1 | -5 | -11 | -55 | -2,707 | -4,111 | -13,535 | -20,555 | -29,777 | -45,221 | -148,885 | -226,105 | -11,128,477 | -55,642,385 | -122,413,247 | -612,066,235 |
