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 110,020,999, 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 | 110,020,999 | |
| -1 | -110,020,999 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,020,999.
Example:
1 x 110,020,999 = 110,020,999
and
-1 x -110,020,999 = 110,020,999
Notice both answers equal 110,020,999
With that explanation out of the way, let's continue. Next, we take the number 110,020,999 and divide it by 2:
110,020,999 ÷ 2 = 55,010,499.5
If the quotient is a whole number, then 2 and 55,010,499.5 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 | 110,020,999 | |
| -1 | -110,020,999 |
Now, we try dividing 110,020,999 by 3:
110,020,999 ÷ 3 = 36,673,666.3333
If the quotient is a whole number, then 3 and 36,673,666.3333 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 | 110,020,999 | |
| -1 | -110,020,999 |
Let's try dividing by 4:
110,020,999 ÷ 4 = 27,505,249.75
If the quotient is a whole number, then 4 and 27,505,249.75 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 | 110,020,999 | |
| -1 | 110,020,999 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 89 | 451 | 979 | 2,741 | 3,649 | 30,151 | 40,139 | 112,381 | 243,949 | 1,236,191 | 2,683,439 | 10,001,909 | 110,020,999 |
| -1 | -11 | -41 | -89 | -451 | -979 | -2,741 | -3,649 | -30,151 | -40,139 | -112,381 | -243,949 | -1,236,191 | -2,683,439 | -10,001,909 | -110,020,999 |
