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 201,424,559, 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 | 201,424,559 | |
| -1 | -201,424,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,424,559.
Example:
1 x 201,424,559 = 201,424,559
and
-1 x -201,424,559 = 201,424,559
Notice both answers equal 201,424,559
With that explanation out of the way, let's continue. Next, we take the number 201,424,559 and divide it by 2:
201,424,559 ÷ 2 = 100,712,279.5
If the quotient is a whole number, then 2 and 100,712,279.5 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 | 201,424,559 | |
| -1 | -201,424,559 |
Now, we try dividing 201,424,559 by 3:
201,424,559 ÷ 3 = 67,141,519.6667
If the quotient is a whole number, then 3 and 67,141,519.6667 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 | 201,424,559 | |
| -1 | -201,424,559 |
Let's try dividing by 4:
201,424,559 ÷ 4 = 50,356,139.75
If the quotient is a whole number, then 4 and 50,356,139.75 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 | 201,424,559 | |
| -1 | 201,424,559 |
If you did it right, you will end up with this table:
| 1 | 7 | 37 | 259 | 523 | 1,487 | 3,661 | 10,409 | 19,351 | 55,019 | 135,457 | 385,133 | 777,701 | 5,443,907 | 28,774,937 | 201,424,559 |
| -1 | -7 | -37 | -259 | -523 | -1,487 | -3,661 | -10,409 | -19,351 | -55,019 | -135,457 | -385,133 | -777,701 | -5,443,907 | -28,774,937 | -201,424,559 |
