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 113,535,245, 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 | 113,535,245 | |
| -1 | -113,535,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,535,245.
Example:
1 x 113,535,245 = 113,535,245
and
-1 x -113,535,245 = 113,535,245
Notice both answers equal 113,535,245
With that explanation out of the way, let's continue. Next, we take the number 113,535,245 and divide it by 2:
113,535,245 ÷ 2 = 56,767,622.5
If the quotient is a whole number, then 2 and 56,767,622.5 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 | 113,535,245 | |
| -1 | -113,535,245 |
Now, we try dividing 113,535,245 by 3:
113,535,245 ÷ 3 = 37,845,081.6667
If the quotient is a whole number, then 3 and 37,845,081.6667 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 | 113,535,245 | |
| -1 | -113,535,245 |
Let's try dividing by 4:
113,535,245 ÷ 4 = 28,383,811.25
If the quotient is a whole number, then 4 and 28,383,811.25 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 | 113,535,245 | |
| -1 | 113,535,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 79 | 115 | 395 | 1,817 | 9,085 | 12,497 | 62,485 | 287,431 | 987,263 | 1,437,155 | 4,936,315 | 22,707,049 | 113,535,245 |
| -1 | -5 | -23 | -79 | -115 | -395 | -1,817 | -9,085 | -12,497 | -62,485 | -287,431 | -987,263 | -1,437,155 | -4,936,315 | -22,707,049 | -113,535,245 |
