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 113,525,399, 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 | 113,525,399 | |
| -1 | -113,525,399 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,525,399.
Example:
1 x 113,525,399 = 113,525,399
and
-1 x -113,525,399 = 113,525,399
Notice both answers equal 113,525,399
With that explanation out of the way, let's continue. Next, we take the number 113,525,399 and divide it by 2:
113,525,399 ÷ 2 = 56,762,699.5
If the quotient is a whole number, then 2 and 56,762,699.5 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 | 113,525,399 | |
| -1 | -113,525,399 |
Now, we try dividing 113,525,399 by 3:
113,525,399 ÷ 3 = 37,841,799.6667
If the quotient is a whole number, then 3 and 37,841,799.6667 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 | 113,525,399 | |
| -1 | -113,525,399 |
Let's try dividing by 4:
113,525,399 ÷ 4 = 28,381,349.75
If the quotient is a whole number, then 4 and 28,381,349.75 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 | 113,525,399 | |
| -1 | 113,525,399 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 247 | 461 | 997 | 5,993 | 8,759 | 12,961 | 18,943 | 113,867 | 246,259 | 459,617 | 5,975,021 | 8,732,723 | 113,525,399 |
| -1 | -13 | -19 | -247 | -461 | -997 | -5,993 | -8,759 | -12,961 | -18,943 | -113,867 | -246,259 | -459,617 | -5,975,021 | -8,732,723 | -113,525,399 |
