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 201,331,153, 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 | 201,331,153 | |
| -1 | -201,331,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,331,153.
Example:
1 x 201,331,153 = 201,331,153
and
-1 x -201,331,153 = 201,331,153
Notice both answers equal 201,331,153
With that explanation out of the way, let's continue. Next, we take the number 201,331,153 and divide it by 2:
201,331,153 ÷ 2 = 100,665,576.5
If the quotient is a whole number, then 2 and 100,665,576.5 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 | 201,331,153 | |
| -1 | -201,331,153 |
Now, we try dividing 201,331,153 by 3:
201,331,153 ÷ 3 = 67,110,384.3333
If the quotient is a whole number, then 3 and 67,110,384.3333 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 | 201,331,153 | |
| -1 | -201,331,153 |
Let's try dividing by 4:
201,331,153 ÷ 4 = 50,332,788.25
If the quotient is a whole number, then 4 and 50,332,788.25 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 | 201,331,153 | |
| -1 | 201,331,153 |
If you did it right, you will end up with this table:
| 1 | 17 | 53 | 73 | 901 | 1,241 | 3,061 | 3,869 | 52,037 | 65,773 | 162,233 | 223,453 | 2,757,961 | 3,798,701 | 11,843,009 | 201,331,153 |
| -1 | -17 | -53 | -73 | -901 | -1,241 | -3,061 | -3,869 | -52,037 | -65,773 | -162,233 | -223,453 | -2,757,961 | -3,798,701 | -11,843,009 | -201,331,153 |
