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 530,715,455, 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 | 530,715,455 | |
| -1 | -530,715,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 530,715,455.
Example:
1 x 530,715,455 = 530,715,455
and
-1 x -530,715,455 = 530,715,455
Notice both answers equal 530,715,455
With that explanation out of the way, let's continue. Next, we take the number 530,715,455 and divide it by 2:
530,715,455 ÷ 2 = 265,357,727.5
If the quotient is a whole number, then 2 and 265,357,727.5 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 | 530,715,455 | |
| -1 | -530,715,455 |
Now, we try dividing 530,715,455 by 3:
530,715,455 ÷ 3 = 176,905,151.6667
If the quotient is a whole number, then 3 and 176,905,151.6667 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 | 530,715,455 | |
| -1 | -530,715,455 |
Let's try dividing by 4:
530,715,455 ÷ 4 = 132,678,863.75
If the quotient is a whole number, then 4 and 132,678,863.75 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 | 530,715,455 | |
| -1 | 530,715,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 89 | 115 | 445 | 2,047 | 10,235 | 51,853 | 259,265 | 1,192,619 | 4,614,917 | 5,963,095 | 23,074,585 | 106,143,091 | 530,715,455 |
| -1 | -5 | -23 | -89 | -115 | -445 | -2,047 | -10,235 | -51,853 | -259,265 | -1,192,619 | -4,614,917 | -5,963,095 | -23,074,585 | -106,143,091 | -530,715,455 |
