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 110,390,945, 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 | 110,390,945 | |
| -1 | -110,390,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,390,945.
Example:
1 x 110,390,945 = 110,390,945
and
-1 x -110,390,945 = 110,390,945
Notice both answers equal 110,390,945
With that explanation out of the way, let's continue. Next, we take the number 110,390,945 and divide it by 2:
110,390,945 ÷ 2 = 55,195,472.5
If the quotient is a whole number, then 2 and 55,195,472.5 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 | 110,390,945 | |
| -1 | -110,390,945 |
Now, we try dividing 110,390,945 by 3:
110,390,945 ÷ 3 = 36,796,981.6667
If the quotient is a whole number, then 3 and 36,796,981.6667 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 | 110,390,945 | |
| -1 | -110,390,945 |
Let's try dividing by 4:
110,390,945 ÷ 4 = 27,597,736.25
If the quotient is a whole number, then 4 and 27,597,736.25 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 | 110,390,945 | |
| -1 | 110,390,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 185,531 | 927,655 | 1,298,717 | 3,154,027 | 6,493,585 | 15,770,135 | 22,078,189 | 110,390,945 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -185,531 | -927,655 | -1,298,717 | -3,154,027 | -6,493,585 | -15,770,135 | -22,078,189 | -110,390,945 |
