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 615,520,361, 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 | 615,520,361 | |
| -1 | -615,520,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 615,520,361.
Example:
1 x 615,520,361 = 615,520,361
and
-1 x -615,520,361 = 615,520,361
Notice both answers equal 615,520,361
With that explanation out of the way, let's continue. Next, we take the number 615,520,361 and divide it by 2:
615,520,361 ÷ 2 = 307,760,180.5
If the quotient is a whole number, then 2 and 307,760,180.5 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 | 615,520,361 | |
| -1 | -615,520,361 |
Now, we try dividing 615,520,361 by 3:
615,520,361 ÷ 3 = 205,173,453.6667
If the quotient is a whole number, then 3 and 205,173,453.6667 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 | 615,520,361 | |
| -1 | -615,520,361 |
Let's try dividing by 4:
615,520,361 ÷ 4 = 153,880,090.25
If the quotient is a whole number, then 4 and 153,880,090.25 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 | 615,520,361 | |
| -1 | 615,520,361 |
If you did it right, you will end up with this table:
| 1 | 43 | 101 | 239 | 593 | 4,343 | 10,277 | 24,139 | 25,499 | 59,893 | 141,727 | 1,037,977 | 2,575,399 | 6,094,261 | 14,314,427 | 615,520,361 |
| -1 | -43 | -101 | -239 | -593 | -4,343 | -10,277 | -24,139 | -25,499 | -59,893 | -141,727 | -1,037,977 | -2,575,399 | -6,094,261 | -14,314,427 | -615,520,361 |
