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 616,204,625, 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 | 616,204,625 | |
| -1 | -616,204,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 616,204,625.
Example:
1 x 616,204,625 = 616,204,625
and
-1 x -616,204,625 = 616,204,625
Notice both answers equal 616,204,625
With that explanation out of the way, let's continue. Next, we take the number 616,204,625 and divide it by 2:
616,204,625 ÷ 2 = 308,102,312.5
If the quotient is a whole number, then 2 and 308,102,312.5 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 | 616,204,625 | |
| -1 | -616,204,625 |
Now, we try dividing 616,204,625 by 3:
616,204,625 ÷ 3 = 205,401,541.6667
If the quotient is a whole number, then 3 and 205,401,541.6667 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 | 616,204,625 | |
| -1 | -616,204,625 |
Let's try dividing by 4:
616,204,625 ÷ 4 = 154,051,156.25
If the quotient is a whole number, then 4 and 154,051,156.25 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 | 616,204,625 | |
| -1 | 616,204,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 97 | 125 | 485 | 2,425 | 12,125 | 50,821 | 254,105 | 1,270,525 | 4,929,637 | 6,352,625 | 24,648,185 | 123,240,925 | 616,204,625 |
| -1 | -5 | -25 | -97 | -125 | -485 | -2,425 | -12,125 | -50,821 | -254,105 | -1,270,525 | -4,929,637 | -6,352,625 | -24,648,185 | -123,240,925 | -616,204,625 |
