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 111,530,455, 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 | 111,530,455 | |
| -1 | -111,530,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 111,530,455.
Example:
1 x 111,530,455 = 111,530,455
and
-1 x -111,530,455 = 111,530,455
Notice both answers equal 111,530,455
With that explanation out of the way, let's continue. Next, we take the number 111,530,455 and divide it by 2:
111,530,455 ÷ 2 = 55,765,227.5
If the quotient is a whole number, then 2 and 55,765,227.5 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 | 111,530,455 | |
| -1 | -111,530,455 |
Now, we try dividing 111,530,455 by 3:
111,530,455 ÷ 3 = 37,176,818.3333
If the quotient is a whole number, then 3 and 37,176,818.3333 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 | 111,530,455 | |
| -1 | -111,530,455 |
Let's try dividing by 4:
111,530,455 ÷ 4 = 27,882,613.75
If the quotient is a whole number, then 4 and 27,882,613.75 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 | 111,530,455 | |
| -1 | 111,530,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 41 | 85 | 205 | 697 | 3,485 | 32,003 | 160,015 | 544,051 | 1,312,123 | 2,720,255 | 6,560,615 | 22,306,091 | 111,530,455 |
| -1 | -5 | -17 | -41 | -85 | -205 | -697 | -3,485 | -32,003 | -160,015 | -544,051 | -1,312,123 | -2,720,255 | -6,560,615 | -22,306,091 | -111,530,455 |
