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 500,030,509, 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 | 500,030,509 | |
| -1 | -500,030,509 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 500,030,509.
Example:
1 x 500,030,509 = 500,030,509
and
-1 x -500,030,509 = 500,030,509
Notice both answers equal 500,030,509
With that explanation out of the way, let's continue. Next, we take the number 500,030,509 and divide it by 2:
500,030,509 ÷ 2 = 250,015,254.5
If the quotient is a whole number, then 2 and 250,015,254.5 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 | 500,030,509 | |
| -1 | -500,030,509 |
Now, we try dividing 500,030,509 by 3:
500,030,509 ÷ 3 = 166,676,836.3333
If the quotient is a whole number, then 3 and 166,676,836.3333 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 | 500,030,509 | |
| -1 | -500,030,509 |
Let's try dividing by 4:
500,030,509 ÷ 4 = 125,007,627.25
If the quotient is a whole number, then 4 and 125,007,627.25 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 | 500,030,509 | |
| -1 | 500,030,509 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 73 | 517 | 803 | 3,431 | 13,249 | 37,741 | 145,739 | 622,703 | 967,177 | 6,849,733 | 10,638,947 | 45,457,319 | 500,030,509 |
| -1 | -11 | -47 | -73 | -517 | -803 | -3,431 | -13,249 | -37,741 | -145,739 | -622,703 | -967,177 | -6,849,733 | -10,638,947 | -45,457,319 | -500,030,509 |
