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 110,858,605, 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 | 110,858,605 | |
| -1 | -110,858,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 110,858,605.
Example:
1 x 110,858,605 = 110,858,605
and
-1 x -110,858,605 = 110,858,605
Notice both answers equal 110,858,605
With that explanation out of the way, let's continue. Next, we take the number 110,858,605 and divide it by 2:
110,858,605 ÷ 2 = 55,429,302.5
If the quotient is a whole number, then 2 and 55,429,302.5 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 | 110,858,605 | |
| -1 | -110,858,605 |
Now, we try dividing 110,858,605 by 3:
110,858,605 ÷ 3 = 36,952,868.3333
If the quotient is a whole number, then 3 and 36,952,868.3333 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 | 110,858,605 | |
| -1 | -110,858,605 |
Let's try dividing by 4:
110,858,605 ÷ 4 = 27,714,651.25
If the quotient is a whole number, then 4 and 27,714,651.25 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 | 110,858,605 | |
| -1 | 110,858,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 155,047 | 775,235 | 1,705,517 | 2,015,611 | 8,527,585 | 10,078,055 | 22,171,721 | 110,858,605 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -155,047 | -775,235 | -1,705,517 | -2,015,611 | -8,527,585 | -10,078,055 | -22,171,721 | -110,858,605 |
