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 616,352,605, 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 | 616,352,605 | |
| -1 | -616,352,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,352,605.
Example:
1 x 616,352,605 = 616,352,605
and
-1 x -616,352,605 = 616,352,605
Notice both answers equal 616,352,605
With that explanation out of the way, let's continue. Next, we take the number 616,352,605 and divide it by 2:
616,352,605 ÷ 2 = 308,176,302.5
If the quotient is a whole number, then 2 and 308,176,302.5 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 | 616,352,605 | |
| -1 | -616,352,605 |
Now, we try dividing 616,352,605 by 3:
616,352,605 ÷ 3 = 205,450,868.3333
If the quotient is a whole number, then 3 and 205,450,868.3333 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 | 616,352,605 | |
| -1 | -616,352,605 |
Let's try dividing by 4:
616,352,605 ÷ 4 = 154,088,151.25
If the quotient is a whole number, then 4 and 154,088,151.25 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 | 616,352,605 | |
| -1 | 616,352,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 83 | 415 | 913 | 4,565 | 135,017 | 675,085 | 1,485,187 | 7,425,935 | 11,206,411 | 56,032,055 | 123,270,521 | 616,352,605 |
| -1 | -5 | -11 | -55 | -83 | -415 | -913 | -4,565 | -135,017 | -675,085 | -1,485,187 | -7,425,935 | -11,206,411 | -56,032,055 | -123,270,521 | -616,352,605 |
