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 614,057,015, 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 | 614,057,015 | |
| -1 | -614,057,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 614,057,015.
Example:
1 x 614,057,015 = 614,057,015
and
-1 x -614,057,015 = 614,057,015
Notice both answers equal 614,057,015
With that explanation out of the way, let's continue. Next, we take the number 614,057,015 and divide it by 2:
614,057,015 ÷ 2 = 307,028,507.5
If the quotient is a whole number, then 2 and 307,028,507.5 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 | 614,057,015 | |
| -1 | -614,057,015 |
Now, we try dividing 614,057,015 by 3:
614,057,015 ÷ 3 = 204,685,671.6667
If the quotient is a whole number, then 3 and 204,685,671.6667 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 | 614,057,015 | |
| -1 | -614,057,015 |
Let's try dividing by 4:
614,057,015 ÷ 4 = 153,514,253.75
If the quotient is a whole number, then 4 and 153,514,253.75 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 | 614,057,015 | |
| -1 | 614,057,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 858,821 | 4,294,105 | 9,447,031 | 11,164,673 | 47,235,155 | 55,823,365 | 122,811,403 | 614,057,015 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -858,821 | -4,294,105 | -9,447,031 | -11,164,673 | -47,235,155 | -55,823,365 | -122,811,403 | -614,057,015 |
