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 513,683,305, 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 | 513,683,305 | |
| -1 | -513,683,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 513,683,305.
Example:
1 x 513,683,305 = 513,683,305
and
-1 x -513,683,305 = 513,683,305
Notice both answers equal 513,683,305
With that explanation out of the way, let's continue. Next, we take the number 513,683,305 and divide it by 2:
513,683,305 ÷ 2 = 256,841,652.5
If the quotient is a whole number, then 2 and 256,841,652.5 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 | 513,683,305 | |
| -1 | -513,683,305 |
Now, we try dividing 513,683,305 by 3:
513,683,305 ÷ 3 = 171,227,768.3333
If the quotient is a whole number, then 3 and 171,227,768.3333 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 | 513,683,305 | |
| -1 | -513,683,305 |
Let's try dividing by 4:
513,683,305 ÷ 4 = 128,420,826.25
If the quotient is a whole number, then 4 and 128,420,826.25 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 | 513,683,305 | |
| -1 | 513,683,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 67 | 85 | 335 | 1,139 | 5,695 | 90,199 | 450,995 | 1,533,383 | 6,043,333 | 7,666,915 | 30,216,665 | 102,736,661 | 513,683,305 |
| -1 | -5 | -17 | -67 | -85 | -335 | -1,139 | -5,695 | -90,199 | -450,995 | -1,533,383 | -6,043,333 | -7,666,915 | -30,216,665 | -102,736,661 | -513,683,305 |
