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 514,315,745, 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 | 514,315,745 | |
| -1 | -514,315,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 514,315,745.
Example:
1 x 514,315,745 = 514,315,745
and
-1 x -514,315,745 = 514,315,745
Notice both answers equal 514,315,745
With that explanation out of the way, let's continue. Next, we take the number 514,315,745 and divide it by 2:
514,315,745 ÷ 2 = 257,157,872.5
If the quotient is a whole number, then 2 and 257,157,872.5 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 | 514,315,745 | |
| -1 | -514,315,745 |
Now, we try dividing 514,315,745 by 3:
514,315,745 ÷ 3 = 171,438,581.6667
If the quotient is a whole number, then 3 and 171,438,581.6667 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 | 514,315,745 | |
| -1 | -514,315,745 |
Let's try dividing by 4:
514,315,745 ÷ 4 = 128,578,936.25
If the quotient is a whole number, then 4 and 128,578,936.25 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 | 514,315,745 | |
| -1 | 514,315,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 167 | 743 | 829 | 835 | 3,715 | 4,145 | 124,081 | 138,443 | 615,947 | 620,405 | 692,215 | 3,079,735 | 102,863,149 | 514,315,745 |
| -1 | -5 | -167 | -743 | -829 | -835 | -3,715 | -4,145 | -124,081 | -138,443 | -615,947 | -620,405 | -692,215 | -3,079,735 | -102,863,149 | -514,315,745 |
