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 111,020,507, 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 | 111,020,507 | |
| -1 | -111,020,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,020,507.
Example:
1 x 111,020,507 = 111,020,507
and
-1 x -111,020,507 = 111,020,507
Notice both answers equal 111,020,507
With that explanation out of the way, let's continue. Next, we take the number 111,020,507 and divide it by 2:
111,020,507 ÷ 2 = 55,510,253.5
If the quotient is a whole number, then 2 and 55,510,253.5 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 | 111,020,507 | |
| -1 | -111,020,507 |
Now, we try dividing 111,020,507 by 3:
111,020,507 ÷ 3 = 37,006,835.6667
If the quotient is a whole number, then 3 and 37,006,835.6667 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 | 111,020,507 | |
| -1 | -111,020,507 |
Let's try dividing by 4:
111,020,507 ÷ 4 = 27,755,126.75
If the quotient is a whole number, then 4 and 27,755,126.75 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 | 111,020,507 | |
| -1 | 111,020,507 |
If you did it right, you will end up with this table:
| 1 | 13 | 103 | 1,339 | 82,913 | 1,077,869 | 8,540,039 | 111,020,507 |
| -1 | -13 | -103 | -1,339 | -82,913 | -1,077,869 | -8,540,039 | -111,020,507 |
