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 111,021,211, 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 | 111,021,211 | |
| -1 | -111,021,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,021,211.
Example:
1 x 111,021,211 = 111,021,211
and
-1 x -111,021,211 = 111,021,211
Notice both answers equal 111,021,211
With that explanation out of the way, let's continue. Next, we take the number 111,021,211 and divide it by 2:
111,021,211 ÷ 2 = 55,510,605.5
If the quotient is a whole number, then 2 and 55,510,605.5 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 | 111,021,211 | |
| -1 | -111,021,211 |
Now, we try dividing 111,021,211 by 3:
111,021,211 ÷ 3 = 37,007,070.3333
If the quotient is a whole number, then 3 and 37,007,070.3333 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 | 111,021,211 | |
| -1 | -111,021,211 |
Let's try dividing by 4:
111,021,211 ÷ 4 = 27,755,302.75
If the quotient is a whole number, then 4 and 27,755,302.75 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 | 111,021,211 | |
| -1 | 111,021,211 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 67 | 343 | 469 | 3,283 | 4,831 | 22,981 | 33,817 | 236,719 | 323,677 | 1,657,033 | 2,265,739 | 15,860,173 | 111,021,211 |
| -1 | -7 | -49 | -67 | -343 | -469 | -3,283 | -4,831 | -22,981 | -33,817 | -236,719 | -323,677 | -1,657,033 | -2,265,739 | -15,860,173 | -111,021,211 |
