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 510,575,075, 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 | 510,575,075 | |
| -1 | -510,575,075 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 510,575,075.
Example:
1 x 510,575,075 = 510,575,075
and
-1 x -510,575,075 = 510,575,075
Notice both answers equal 510,575,075
With that explanation out of the way, let's continue. Next, we take the number 510,575,075 and divide it by 2:
510,575,075 ÷ 2 = 255,287,537.5
If the quotient is a whole number, then 2 and 255,287,537.5 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 | 510,575,075 | |
| -1 | -510,575,075 |
Now, we try dividing 510,575,075 by 3:
510,575,075 ÷ 3 = 170,191,691.6667
If the quotient is a whole number, then 3 and 170,191,691.6667 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 | 510,575,075 | |
| -1 | -510,575,075 |
Let's try dividing by 4:
510,575,075 ÷ 4 = 127,643,768.75
If the quotient is a whole number, then 4 and 127,643,768.75 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 | 510,575,075 | |
| -1 | 510,575,075 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 545 | 2,725 | 187,367 | 936,835 | 4,684,175 | 20,423,003 | 102,115,015 | 510,575,075 |
| -1 | -5 | -25 | -109 | -545 | -2,725 | -187,367 | -936,835 | -4,684,175 | -20,423,003 | -102,115,015 | -510,575,075 |
