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 201,304,243, 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 | 201,304,243 | |
| -1 | -201,304,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,304,243.
Example:
1 x 201,304,243 = 201,304,243
and
-1 x -201,304,243 = 201,304,243
Notice both answers equal 201,304,243
With that explanation out of the way, let's continue. Next, we take the number 201,304,243 and divide it by 2:
201,304,243 ÷ 2 = 100,652,121.5
If the quotient is a whole number, then 2 and 100,652,121.5 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 | 201,304,243 | |
| -1 | -201,304,243 |
Now, we try dividing 201,304,243 by 3:
201,304,243 ÷ 3 = 67,101,414.3333
If the quotient is a whole number, then 3 and 67,101,414.3333 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 | 201,304,243 | |
| -1 | -201,304,243 |
Let's try dividing by 4:
201,304,243 ÷ 4 = 50,326,060.75
If the quotient is a whole number, then 4 and 50,326,060.75 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 | 201,304,243 | |
| -1 | 201,304,243 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 329 | 709 | 863 | 4,963 | 6,041 | 33,323 | 40,561 | 233,261 | 283,927 | 611,867 | 4,283,069 | 28,757,749 | 201,304,243 |
| -1 | -7 | -47 | -329 | -709 | -863 | -4,963 | -6,041 | -33,323 | -40,561 | -233,261 | -283,927 | -611,867 | -4,283,069 | -28,757,749 | -201,304,243 |
