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 113,433,215, 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 | 113,433,215 | |
| -1 | -113,433,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,433,215.
Example:
1 x 113,433,215 = 113,433,215
and
-1 x -113,433,215 = 113,433,215
Notice both answers equal 113,433,215
With that explanation out of the way, let's continue. Next, we take the number 113,433,215 and divide it by 2:
113,433,215 ÷ 2 = 56,716,607.5
If the quotient is a whole number, then 2 and 56,716,607.5 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 | 113,433,215 | |
| -1 | -113,433,215 |
Now, we try dividing 113,433,215 by 3:
113,433,215 ÷ 3 = 37,811,071.6667
If the quotient is a whole number, then 3 and 37,811,071.6667 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 | 113,433,215 | |
| -1 | -113,433,215 |
Let's try dividing by 4:
113,433,215 ÷ 4 = 28,358,303.75
If the quotient is a whole number, then 4 and 28,358,303.75 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 | 113,433,215 | |
| -1 | 113,433,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 263 | 1,315 | 1,841 | 9,205 | 12,323 | 61,615 | 86,261 | 431,305 | 3,240,949 | 16,204,745 | 22,686,643 | 113,433,215 |
| -1 | -5 | -7 | -35 | -263 | -1,315 | -1,841 | -9,205 | -12,323 | -61,615 | -86,261 | -431,305 | -3,240,949 | -16,204,745 | -22,686,643 | -113,433,215 |
