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 110,165,155, 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 | 110,165,155 | |
| -1 | -110,165,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,165,155.
Example:
1 x 110,165,155 = 110,165,155
and
-1 x -110,165,155 = 110,165,155
Notice both answers equal 110,165,155
With that explanation out of the way, let's continue. Next, we take the number 110,165,155 and divide it by 2:
110,165,155 ÷ 2 = 55,082,577.5
If the quotient is a whole number, then 2 and 55,082,577.5 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 | 110,165,155 | |
| -1 | -110,165,155 |
Now, we try dividing 110,165,155 by 3:
110,165,155 ÷ 3 = 36,721,718.3333
If the quotient is a whole number, then 3 and 36,721,718.3333 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 | 110,165,155 | |
| -1 | -110,165,155 |
Let's try dividing by 4:
110,165,155 ÷ 4 = 27,541,288.75
If the quotient is a whole number, then 4 and 27,541,288.75 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 | 110,165,155 | |
| -1 | 110,165,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 251 | 1,255 | 2,141 | 10,291 | 10,705 | 51,455 | 87,781 | 438,905 | 537,391 | 2,686,955 | 22,033,031 | 110,165,155 |
| -1 | -5 | -41 | -205 | -251 | -1,255 | -2,141 | -10,291 | -10,705 | -51,455 | -87,781 | -438,905 | -537,391 | -2,686,955 | -22,033,031 | -110,165,155 |
