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 201,304,415, 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 | 201,304,415 | |
| -1 | -201,304,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,304,415.
Example:
1 x 201,304,415 = 201,304,415
and
-1 x -201,304,415 = 201,304,415
Notice both answers equal 201,304,415
With that explanation out of the way, let's continue. Next, we take the number 201,304,415 and divide it by 2:
201,304,415 ÷ 2 = 100,652,207.5
If the quotient is a whole number, then 2 and 100,652,207.5 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 | 201,304,415 | |
| -1 | -201,304,415 |
Now, we try dividing 201,304,415 by 3:
201,304,415 ÷ 3 = 67,101,471.6667
If the quotient is a whole number, then 3 and 67,101,471.6667 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 | 201,304,415 | |
| -1 | -201,304,415 |
Let's try dividing by 4:
201,304,415 ÷ 4 = 50,326,103.75
If the quotient is a whole number, then 4 and 50,326,103.75 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 | 201,304,415 | |
| -1 | 201,304,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 113 | 565 | 1,469 | 7,345 | 27,407 | 137,035 | 356,291 | 1,781,455 | 3,096,991 | 15,484,955 | 40,260,883 | 201,304,415 |
| -1 | -5 | -13 | -65 | -113 | -565 | -1,469 | -7,345 | -27,407 | -137,035 | -356,291 | -1,781,455 | -3,096,991 | -15,484,955 | -40,260,883 | -201,304,415 |
