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 113,133,415, 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 | 113,133,415 | |
| -1 | -113,133,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,133,415.
Example:
1 x 113,133,415 = 113,133,415
and
-1 x -113,133,415 = 113,133,415
Notice both answers equal 113,133,415
With that explanation out of the way, let's continue. Next, we take the number 113,133,415 and divide it by 2:
113,133,415 ÷ 2 = 56,566,707.5
If the quotient is a whole number, then 2 and 56,566,707.5 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 | 113,133,415 | |
| -1 | -113,133,415 |
Now, we try dividing 113,133,415 by 3:
113,133,415 ÷ 3 = 37,711,138.3333
If the quotient is a whole number, then 3 and 37,711,138.3333 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 | 113,133,415 | |
| -1 | -113,133,415 |
Let's try dividing by 4:
113,133,415 ÷ 4 = 28,283,353.75
If the quotient is a whole number, then 4 and 28,283,353.75 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 | 113,133,415 | |
| -1 | 113,133,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 157 | 785 | 4,649 | 4,867 | 23,245 | 24,335 | 144,119 | 720,595 | 729,893 | 3,649,465 | 22,626,683 | 113,133,415 |
| -1 | -5 | -31 | -155 | -157 | -785 | -4,649 | -4,867 | -23,245 | -24,335 | -144,119 | -720,595 | -729,893 | -3,649,465 | -22,626,683 | -113,133,415 |
