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 110,866,021, 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 | 110,866,021 | |
| -1 | -110,866,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,866,021.
Example:
1 x 110,866,021 = 110,866,021
and
-1 x -110,866,021 = 110,866,021
Notice both answers equal 110,866,021
With that explanation out of the way, let's continue. Next, we take the number 110,866,021 and divide it by 2:
110,866,021 ÷ 2 = 55,433,010.5
If the quotient is a whole number, then 2 and 55,433,010.5 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 | 110,866,021 | |
| -1 | -110,866,021 |
Now, we try dividing 110,866,021 by 3:
110,866,021 ÷ 3 = 36,955,340.3333
If the quotient is a whole number, then 3 and 36,955,340.3333 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 | 110,866,021 | |
| -1 | -110,866,021 |
Let's try dividing by 4:
110,866,021 ÷ 4 = 27,716,505.25
If the quotient is a whole number, then 4 and 27,716,505.25 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 | 110,866,021 | |
| -1 | 110,866,021 |
If you did it right, you will end up with this table:
| 1 | 7 | 157 | 281 | 359 | 1,099 | 1,967 | 2,513 | 44,117 | 56,363 | 100,879 | 308,819 | 394,541 | 706,153 | 15,838,003 | 110,866,021 |
| -1 | -7 | -157 | -281 | -359 | -1,099 | -1,967 | -2,513 | -44,117 | -56,363 | -100,879 | -308,819 | -394,541 | -706,153 | -15,838,003 | -110,866,021 |
