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 111,434,155, 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 | 111,434,155 | |
| -1 | -111,434,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,434,155.
Example:
1 x 111,434,155 = 111,434,155
and
-1 x -111,434,155 = 111,434,155
Notice both answers equal 111,434,155
With that explanation out of the way, let's continue. Next, we take the number 111,434,155 and divide it by 2:
111,434,155 ÷ 2 = 55,717,077.5
If the quotient is a whole number, then 2 and 55,717,077.5 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 | 111,434,155 | |
| -1 | -111,434,155 |
Now, we try dividing 111,434,155 by 3:
111,434,155 ÷ 3 = 37,144,718.3333
If the quotient is a whole number, then 3 and 37,144,718.3333 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 | 111,434,155 | |
| -1 | -111,434,155 |
Let's try dividing by 4:
111,434,155 ÷ 4 = 27,858,538.75
If the quotient is a whole number, then 4 and 27,858,538.75 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 | 111,434,155 | |
| -1 | 111,434,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 3,605 | 30,911 | 154,555 | 216,377 | 1,081,885 | 3,183,833 | 15,919,165 | 22,286,831 | 111,434,155 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -3,605 | -30,911 | -154,555 | -216,377 | -1,081,885 | -3,183,833 | -15,919,165 | -22,286,831 | -111,434,155 |
