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 188,247,847, 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 | 188,247,847 | |
| -1 | -188,247,847 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 188,247,847.
Example:
1 x 188,247,847 = 188,247,847
and
-1 x -188,247,847 = 188,247,847
Notice both answers equal 188,247,847
With that explanation out of the way, let's continue. Next, we take the number 188,247,847 and divide it by 2:
188,247,847 ÷ 2 = 94,123,923.5
If the quotient is a whole number, then 2 and 94,123,923.5 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 | 188,247,847 | |
| -1 | -188,247,847 |
Now, we try dividing 188,247,847 by 3:
188,247,847 ÷ 3 = 62,749,282.3333
If the quotient is a whole number, then 3 and 62,749,282.3333 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 | 188,247,847 | |
| -1 | -188,247,847 |
Let's try dividing by 4:
188,247,847 ÷ 4 = 47,061,961.75
If the quotient is a whole number, then 4 and 47,061,961.75 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 | 188,247,847 | |
| -1 | 188,247,847 |
If you did it right, you will end up with this table:
| 1 | 23 | 103 | 229 | 347 | 2,369 | 5,267 | 7,981 | 23,587 | 35,741 | 79,463 | 542,501 | 822,043 | 1,827,649 | 8,184,689 | 188,247,847 |
| -1 | -23 | -103 | -229 | -347 | -2,369 | -5,267 | -7,981 | -23,587 | -35,741 | -79,463 | -542,501 | -822,043 | -1,827,649 | -8,184,689 | -188,247,847 |
