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 510,717,349, 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 | 510,717,349 | |
| -1 | -510,717,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 510,717,349.
Example:
1 x 510,717,349 = 510,717,349
and
-1 x -510,717,349 = 510,717,349
Notice both answers equal 510,717,349
With that explanation out of the way, let's continue. Next, we take the number 510,717,349 and divide it by 2:
510,717,349 ÷ 2 = 255,358,674.5
If the quotient is a whole number, then 2 and 255,358,674.5 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 | 510,717,349 | |
| -1 | -510,717,349 |
Now, we try dividing 510,717,349 by 3:
510,717,349 ÷ 3 = 170,239,116.3333
If the quotient is a whole number, then 3 and 170,239,116.3333 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 | 510,717,349 | |
| -1 | -510,717,349 |
Let's try dividing by 4:
510,717,349 ÷ 4 = 127,679,337.25
If the quotient is a whole number, then 4 and 127,679,337.25 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 | 510,717,349 | |
| -1 | 510,717,349 |
If you did it right, you will end up with this table:
| 1 | 17 | 67 | 359 | 1,139 | 1,249 | 6,103 | 21,233 | 24,053 | 83,683 | 408,901 | 448,391 | 1,422,611 | 7,622,647 | 30,042,197 | 510,717,349 |
| -1 | -17 | -67 | -359 | -1,139 | -1,249 | -6,103 | -21,233 | -24,053 | -83,683 | -408,901 | -448,391 | -1,422,611 | -7,622,647 | -30,042,197 | -510,717,349 |
