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 615,324,353, 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 | 615,324,353 | |
| -1 | -615,324,353 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 615,324,353.
Example:
1 x 615,324,353 = 615,324,353
and
-1 x -615,324,353 = 615,324,353
Notice both answers equal 615,324,353
With that explanation out of the way, let's continue. Next, we take the number 615,324,353 and divide it by 2:
615,324,353 ÷ 2 = 307,662,176.5
If the quotient is a whole number, then 2 and 307,662,176.5 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 | 615,324,353 | |
| -1 | -615,324,353 |
Now, we try dividing 615,324,353 by 3:
615,324,353 ÷ 3 = 205,108,117.6667
If the quotient is a whole number, then 3 and 205,108,117.6667 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 | 615,324,353 | |
| -1 | -615,324,353 |
Let's try dividing by 4:
615,324,353 ÷ 4 = 153,831,088.25
If the quotient is a whole number, then 4 and 153,831,088.25 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 | 615,324,353 | |
| -1 | 615,324,353 |
If you did it right, you will end up with this table:
| 1 | 7 | 283 | 383 | 811 | 1,981 | 2,681 | 5,677 | 108,389 | 229,513 | 310,613 | 758,723 | 1,606,591 | 2,174,291 | 87,903,479 | 615,324,353 |
| -1 | -7 | -283 | -383 | -811 | -1,981 | -2,681 | -5,677 | -108,389 | -229,513 | -310,613 | -758,723 | -1,606,591 | -2,174,291 | -87,903,479 | -615,324,353 |
