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 188,252,405, 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 | 188,252,405 | |
| -1 | -188,252,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 188,252,405.
Example:
1 x 188,252,405 = 188,252,405
and
-1 x -188,252,405 = 188,252,405
Notice both answers equal 188,252,405
With that explanation out of the way, let's continue. Next, we take the number 188,252,405 and divide it by 2:
188,252,405 ÷ 2 = 94,126,202.5
If the quotient is a whole number, then 2 and 94,126,202.5 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 | 188,252,405 | |
| -1 | -188,252,405 |
Now, we try dividing 188,252,405 by 3:
188,252,405 ÷ 3 = 62,750,801.6667
If the quotient is a whole number, then 3 and 62,750,801.6667 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 | 188,252,405 | |
| -1 | -188,252,405 |
Let's try dividing by 4:
188,252,405 ÷ 4 = 47,063,101.25
If the quotient is a whole number, then 4 and 47,063,101.25 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 | 188,252,405 | |
| -1 | 188,252,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 121 | 305 | 605 | 671 | 3,355 | 5,101 | 7,381 | 25,505 | 36,905 | 56,111 | 280,555 | 311,161 | 617,221 | 1,555,805 | 3,086,105 | 3,422,771 | 17,113,855 | 37,650,481 | 188,252,405 |
| -1 | -5 | -11 | -55 | -61 | -121 | -305 | -605 | -671 | -3,355 | -5,101 | -7,381 | -25,505 | -36,905 | -56,111 | -280,555 | -311,161 | -617,221 | -1,555,805 | -3,086,105 | -3,422,771 | -17,113,855 | -37,650,481 | -188,252,405 |
