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 510,357,835, 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 | 510,357,835 | |
| -1 | -510,357,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 510,357,835.
Example:
1 x 510,357,835 = 510,357,835
and
-1 x -510,357,835 = 510,357,835
Notice both answers equal 510,357,835
With that explanation out of the way, let's continue. Next, we take the number 510,357,835 and divide it by 2:
510,357,835 ÷ 2 = 255,178,917.5
If the quotient is a whole number, then 2 and 255,178,917.5 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 | 510,357,835 | |
| -1 | -510,357,835 |
Now, we try dividing 510,357,835 by 3:
510,357,835 ÷ 3 = 170,119,278.3333
If the quotient is a whole number, then 3 and 170,119,278.3333 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 | 510,357,835 | |
| -1 | -510,357,835 |
Let's try dividing by 4:
510,357,835 ÷ 4 = 127,589,458.75
If the quotient is a whole number, then 4 and 127,589,458.75 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 | 510,357,835 | |
| -1 | 510,357,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 212,207 | 1,061,035 | 2,758,691 | 7,851,659 | 13,793,455 | 39,258,295 | 102,071,567 | 510,357,835 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -212,207 | -1,061,035 | -2,758,691 | -7,851,659 | -13,793,455 | -39,258,295 | -102,071,567 | -510,357,835 |
