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 510,246,503, 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 | 510,246,503 | |
| -1 | -510,246,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 510,246,503.
Example:
1 x 510,246,503 = 510,246,503
and
-1 x -510,246,503 = 510,246,503
Notice both answers equal 510,246,503
With that explanation out of the way, let's continue. Next, we take the number 510,246,503 and divide it by 2:
510,246,503 ÷ 2 = 255,123,251.5
If the quotient is a whole number, then 2 and 255,123,251.5 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 | 510,246,503 | |
| -1 | -510,246,503 |
Now, we try dividing 510,246,503 by 3:
510,246,503 ÷ 3 = 170,082,167.6667
If the quotient is a whole number, then 3 and 170,082,167.6667 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 | 510,246,503 | |
| -1 | -510,246,503 |
Let's try dividing by 4:
510,246,503 ÷ 4 = 127,561,625.75
If the quotient is a whole number, then 4 and 127,561,625.75 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 | 510,246,503 | |
| -1 | 510,246,503 |
If you did it right, you will end up with this table:
| 1 | 13 | 29 | 127 | 377 | 1,651 | 3,683 | 10,657 | 47,879 | 138,541 | 309,053 | 1,353,439 | 4,017,689 | 17,594,707 | 39,249,731 | 510,246,503 |
| -1 | -13 | -29 | -127 | -377 | -1,651 | -3,683 | -10,657 | -47,879 | -138,541 | -309,053 | -1,353,439 | -4,017,689 | -17,594,707 | -39,249,731 | -510,246,503 |
