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 513,114,239, 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 | 513,114,239 | |
| -1 | -513,114,239 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 513,114,239.
Example:
1 x 513,114,239 = 513,114,239
and
-1 x -513,114,239 = 513,114,239
Notice both answers equal 513,114,239
With that explanation out of the way, let's continue. Next, we take the number 513,114,239 and divide it by 2:
513,114,239 ÷ 2 = 256,557,119.5
If the quotient is a whole number, then 2 and 256,557,119.5 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 | 513,114,239 | |
| -1 | -513,114,239 |
Now, we try dividing 513,114,239 by 3:
513,114,239 ÷ 3 = 171,038,079.6667
If the quotient is a whole number, then 3 and 171,038,079.6667 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 | 513,114,239 | |
| -1 | -513,114,239 |
Let's try dividing by 4:
513,114,239 ÷ 4 = 128,278,559.75
If the quotient is a whole number, then 4 and 128,278,559.75 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 | 513,114,239 | |
| -1 | 513,114,239 |
If you did it right, you will end up with this table:
| 1 | 11 | 101 | 193 | 1,111 | 2,123 | 2,393 | 19,493 | 26,323 | 214,423 | 241,693 | 461,849 | 2,658,623 | 5,080,339 | 46,646,749 | 513,114,239 |
| -1 | -11 | -101 | -193 | -1,111 | -2,123 | -2,393 | -19,493 | -26,323 | -214,423 | -241,693 | -461,849 | -2,658,623 | -5,080,339 | -46,646,749 | -513,114,239 |
