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 205,244,315, 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 | 205,244,315 | |
| -1 | -205,244,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 205,244,315.
Example:
1 x 205,244,315 = 205,244,315
and
-1 x -205,244,315 = 205,244,315
Notice both answers equal 205,244,315
With that explanation out of the way, let's continue. Next, we take the number 205,244,315 and divide it by 2:
205,244,315 ÷ 2 = 102,622,157.5
If the quotient is a whole number, then 2 and 102,622,157.5 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 | 205,244,315 | |
| -1 | -205,244,315 |
Now, we try dividing 205,244,315 by 3:
205,244,315 ÷ 3 = 68,414,771.6667
If the quotient is a whole number, then 3 and 68,414,771.6667 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 | 205,244,315 | |
| -1 | -205,244,315 |
Let's try dividing by 4:
205,244,315 ÷ 4 = 51,311,078.75
If the quotient is a whole number, then 4 and 51,311,078.75 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 | 205,244,315 | |
| -1 | 205,244,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 355 | 479 | 1,207 | 2,395 | 5,041 | 6,035 | 8,143 | 25,205 | 34,009 | 40,715 | 85,697 | 170,045 | 428,485 | 578,153 | 2,414,639 | 2,890,765 | 12,073,195 | 41,048,863 | 205,244,315 |
| -1 | -5 | -17 | -71 | -85 | -355 | -479 | -1,207 | -2,395 | -5,041 | -6,035 | -8,143 | -25,205 | -34,009 | -40,715 | -85,697 | -170,045 | -428,485 | -578,153 | -2,414,639 | -2,890,765 | -12,073,195 | -41,048,863 | -205,244,315 |
