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 188,433,011, 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 | 188,433,011 | |
| -1 | -188,433,011 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 188,433,011.
Example:
1 x 188,433,011 = 188,433,011
and
-1 x -188,433,011 = 188,433,011
Notice both answers equal 188,433,011
With that explanation out of the way, let's continue. Next, we take the number 188,433,011 and divide it by 2:
188,433,011 ÷ 2 = 94,216,505.5
If the quotient is a whole number, then 2 and 94,216,505.5 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 | 188,433,011 | |
| -1 | -188,433,011 |
Now, we try dividing 188,433,011 by 3:
188,433,011 ÷ 3 = 62,811,003.6667
If the quotient is a whole number, then 3 and 62,811,003.6667 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 | 188,433,011 | |
| -1 | -188,433,011 |
Let's try dividing by 4:
188,433,011 ÷ 4 = 47,108,252.75
If the quotient is a whole number, then 4 and 47,108,252.75 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 | 188,433,011 | |
| -1 | 188,433,011 |
If you did it right, you will end up with this table:
| 1 | 13 | 47 | 67 | 611 | 871 | 3,149 | 4,603 | 40,937 | 59,839 | 216,341 | 308,401 | 2,812,433 | 4,009,213 | 14,494,847 | 188,433,011 |
| -1 | -13 | -47 | -67 | -611 | -871 | -3,149 | -4,603 | -40,937 | -59,839 | -216,341 | -308,401 | -2,812,433 | -4,009,213 | -14,494,847 | -188,433,011 |
