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 111,001,211, 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 | 111,001,211 | |
| -1 | -111,001,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,001,211.
Example:
1 x 111,001,211 = 111,001,211
and
-1 x -111,001,211 = 111,001,211
Notice both answers equal 111,001,211
With that explanation out of the way, let's continue. Next, we take the number 111,001,211 and divide it by 2:
111,001,211 ÷ 2 = 55,500,605.5
If the quotient is a whole number, then 2 and 55,500,605.5 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 | 111,001,211 | |
| -1 | -111,001,211 |
Now, we try dividing 111,001,211 by 3:
111,001,211 ÷ 3 = 37,000,403.6667
If the quotient is a whole number, then 3 and 37,000,403.6667 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 | 111,001,211 | |
| -1 | -111,001,211 |
Let's try dividing by 4:
111,001,211 ÷ 4 = 27,750,302.75
If the quotient is a whole number, then 4 and 27,750,302.75 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 | 111,001,211 | |
| -1 | 111,001,211 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 401 | 857 | 6,817 | 7,619 | 14,569 | 16,283 | 129,523 | 276,811 | 343,657 | 5,842,169 | 6,529,483 | 111,001,211 |
| -1 | -17 | -19 | -323 | -401 | -857 | -6,817 | -7,619 | -14,569 | -16,283 | -129,523 | -276,811 | -343,657 | -5,842,169 | -6,529,483 | -111,001,211 |
