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 112,015,255, 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 | 112,015,255 | |
| -1 | -112,015,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,015,255.
Example:
1 x 112,015,255 = 112,015,255
and
-1 x -112,015,255 = 112,015,255
Notice both answers equal 112,015,255
With that explanation out of the way, let's continue. Next, we take the number 112,015,255 and divide it by 2:
112,015,255 ÷ 2 = 56,007,627.5
If the quotient is a whole number, then 2 and 56,007,627.5 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 | 112,015,255 | |
| -1 | -112,015,255 |
Now, we try dividing 112,015,255 by 3:
112,015,255 ÷ 3 = 37,338,418.3333
If the quotient is a whole number, then 3 and 37,338,418.3333 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 | 112,015,255 | |
| -1 | -112,015,255 |
Let's try dividing by 4:
112,015,255 ÷ 4 = 28,003,813.75
If the quotient is a whole number, then 4 and 28,003,813.75 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 | 112,015,255 | |
| -1 | 112,015,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 70,229 | 351,145 | 772,519 | 2,036,641 | 3,862,595 | 10,183,205 | 22,403,051 | 112,015,255 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -70,229 | -351,145 | -772,519 | -2,036,641 | -3,862,595 | -10,183,205 | -22,403,051 | -112,015,255 |
