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 201,110,119, 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 | 201,110,119 | |
| -1 | -201,110,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 201,110,119.
Example:
1 x 201,110,119 = 201,110,119
and
-1 x -201,110,119 = 201,110,119
Notice both answers equal 201,110,119
With that explanation out of the way, let's continue. Next, we take the number 201,110,119 and divide it by 2:
201,110,119 ÷ 2 = 100,555,059.5
If the quotient is a whole number, then 2 and 100,555,059.5 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 | 201,110,119 | |
| -1 | -201,110,119 |
Now, we try dividing 201,110,119 by 3:
201,110,119 ÷ 3 = 67,036,706.3333
If the quotient is a whole number, then 3 and 67,036,706.3333 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 | 201,110,119 | |
| -1 | -201,110,119 |
Let's try dividing by 4:
201,110,119 ÷ 4 = 50,277,529.75
If the quotient is a whole number, then 4 and 50,277,529.75 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 | 201,110,119 | |
| -1 | 201,110,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 809 | 2,089 | 5,663 | 13,753 | 14,623 | 35,513 | 96,271 | 248,591 | 1,690,001 | 11,830,007 | 28,730,017 | 201,110,119 |
| -1 | -7 | -17 | -119 | -809 | -2,089 | -5,663 | -13,753 | -14,623 | -35,513 | -96,271 | -248,591 | -1,690,001 | -11,830,007 | -28,730,017 | -201,110,119 |
