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 110,621,665, 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 | 110,621,665 | |
| -1 | -110,621,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,621,665.
Example:
1 x 110,621,665 = 110,621,665
and
-1 x -110,621,665 = 110,621,665
Notice both answers equal 110,621,665
With that explanation out of the way, let's continue. Next, we take the number 110,621,665 and divide it by 2:
110,621,665 ÷ 2 = 55,310,832.5
If the quotient is a whole number, then 2 and 55,310,832.5 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 | 110,621,665 | |
| -1 | -110,621,665 |
Now, we try dividing 110,621,665 by 3:
110,621,665 ÷ 3 = 36,873,888.3333
If the quotient is a whole number, then 3 and 36,873,888.3333 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 | 110,621,665 | |
| -1 | -110,621,665 |
Let's try dividing by 4:
110,621,665 ÷ 4 = 27,655,416.25
If the quotient is a whole number, then 4 and 27,655,416.25 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 | 110,621,665 | |
| -1 | 110,621,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 245 | 385 | 539 | 2,695 | 41,047 | 205,235 | 287,329 | 451,517 | 1,436,645 | 2,011,303 | 2,257,585 | 3,160,619 | 10,056,515 | 15,803,095 | 22,124,333 | 110,621,665 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -245 | -385 | -539 | -2,695 | -41,047 | -205,235 | -287,329 | -451,517 | -1,436,645 | -2,011,303 | -2,257,585 | -3,160,619 | -10,056,515 | -15,803,095 | -22,124,333 | -110,621,665 |
