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 112,120,235, 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 | 112,120,235 | |
| -1 | -112,120,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 112,120,235.
Example:
1 x 112,120,235 = 112,120,235
and
-1 x -112,120,235 = 112,120,235
Notice both answers equal 112,120,235
With that explanation out of the way, let's continue. Next, we take the number 112,120,235 and divide it by 2:
112,120,235 ÷ 2 = 56,060,117.5
If the quotient is a whole number, then 2 and 56,060,117.5 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 | 112,120,235 | |
| -1 | -112,120,235 |
Now, we try dividing 112,120,235 by 3:
112,120,235 ÷ 3 = 37,373,411.6667
If the quotient is a whole number, then 3 and 37,373,411.6667 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 | 112,120,235 | |
| -1 | -112,120,235 |
Let's try dividing by 4:
112,120,235 ÷ 4 = 28,030,058.75
If the quotient is a whole number, then 4 and 28,030,058.75 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 | 112,120,235 | |
| -1 | 112,120,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 29 | 95 | 145 | 551 | 2,755 | 40,697 | 203,485 | 773,243 | 1,180,213 | 3,866,215 | 5,901,065 | 22,424,047 | 112,120,235 |
| -1 | -5 | -19 | -29 | -95 | -145 | -551 | -2,755 | -40,697 | -203,485 | -773,243 | -1,180,213 | -3,866,215 | -5,901,065 | -22,424,047 | -112,120,235 |
