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 113,615,611, 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 | 113,615,611 | |
| -1 | -113,615,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,615,611.
Example:
1 x 113,615,611 = 113,615,611
and
-1 x -113,615,611 = 113,615,611
Notice both answers equal 113,615,611
With that explanation out of the way, let's continue. Next, we take the number 113,615,611 and divide it by 2:
113,615,611 ÷ 2 = 56,807,805.5
If the quotient is a whole number, then 2 and 56,807,805.5 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 | 113,615,611 | |
| -1 | -113,615,611 |
Now, we try dividing 113,615,611 by 3:
113,615,611 ÷ 3 = 37,871,870.3333
If the quotient is a whole number, then 3 and 37,871,870.3333 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 | 113,615,611 | |
| -1 | -113,615,611 |
Let's try dividing by 4:
113,615,611 ÷ 4 = 28,403,902.75
If the quotient is a whole number, then 4 and 28,403,902.75 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 | 113,615,611 | |
| -1 | 113,615,611 |
If you did it right, you will end up with this table:
| 1 | 19 | 61 | 167 | 587 | 1,159 | 3,173 | 10,187 | 11,153 | 35,807 | 98,029 | 193,553 | 680,333 | 1,862,551 | 5,979,769 | 113,615,611 |
| -1 | -19 | -61 | -167 | -587 | -1,159 | -3,173 | -10,187 | -11,153 | -35,807 | -98,029 | -193,553 | -680,333 | -1,862,551 | -5,979,769 | -113,615,611 |
