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 615,200,435, 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 | 615,200,435 | |
| -1 | -615,200,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 615,200,435.
Example:
1 x 615,200,435 = 615,200,435
and
-1 x -615,200,435 = 615,200,435
Notice both answers equal 615,200,435
With that explanation out of the way, let's continue. Next, we take the number 615,200,435 and divide it by 2:
615,200,435 ÷ 2 = 307,600,217.5
If the quotient is a whole number, then 2 and 307,600,217.5 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 | 615,200,435 | |
| -1 | -615,200,435 |
Now, we try dividing 615,200,435 by 3:
615,200,435 ÷ 3 = 205,066,811.6667
If the quotient is a whole number, then 3 and 205,066,811.6667 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 | 615,200,435 | |
| -1 | -615,200,435 |
Let's try dividing by 4:
615,200,435 ÷ 4 = 153,800,108.75
If the quotient is a whole number, then 4 and 153,800,108.75 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 | 615,200,435 | |
| -1 | 615,200,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 2,293 | 2,333 | 11,465 | 11,665 | 52,739 | 53,659 | 263,695 | 268,295 | 5,349,569 | 26,747,845 | 123,040,087 | 615,200,435 |
| -1 | -5 | -23 | -115 | -2,293 | -2,333 | -11,465 | -11,665 | -52,739 | -53,659 | -263,695 | -268,295 | -5,349,569 | -26,747,845 | -123,040,087 | -615,200,435 |
