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 111,026,245, 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 | 111,026,245 | |
| -1 | -111,026,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,026,245.
Example:
1 x 111,026,245 = 111,026,245
and
-1 x -111,026,245 = 111,026,245
Notice both answers equal 111,026,245
With that explanation out of the way, let's continue. Next, we take the number 111,026,245 and divide it by 2:
111,026,245 ÷ 2 = 55,513,122.5
If the quotient is a whole number, then 2 and 55,513,122.5 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 | 111,026,245 | |
| -1 | -111,026,245 |
Now, we try dividing 111,026,245 by 3:
111,026,245 ÷ 3 = 37,008,748.3333
If the quotient is a whole number, then 3 and 37,008,748.3333 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 | 111,026,245 | |
| -1 | -111,026,245 |
Let's try dividing by 4:
111,026,245 ÷ 4 = 27,756,561.25
If the quotient is a whole number, then 4 and 27,756,561.25 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 | 111,026,245 | |
| -1 | 111,026,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 197 | 985 | 2,167 | 10,247 | 10,835 | 51,235 | 112,717 | 563,585 | 2,018,659 | 10,093,295 | 22,205,249 | 111,026,245 |
| -1 | -5 | -11 | -55 | -197 | -985 | -2,167 | -10,247 | -10,835 | -51,235 | -112,717 | -563,585 | -2,018,659 | -10,093,295 | -22,205,249 | -111,026,245 |
