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 237,831,737, 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 | 237,831,737 | |
| -1 | -237,831,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,831,737.
Example:
1 x 237,831,737 = 237,831,737
and
-1 x -237,831,737 = 237,831,737
Notice both answers equal 237,831,737
With that explanation out of the way, let's continue. Next, we take the number 237,831,737 and divide it by 2:
237,831,737 ÷ 2 = 118,915,868.5
If the quotient is a whole number, then 2 and 118,915,868.5 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 | 237,831,737 | |
| -1 | -237,831,737 |
Now, we try dividing 237,831,737 by 3:
237,831,737 ÷ 3 = 79,277,245.6667
If the quotient is a whole number, then 3 and 79,277,245.6667 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 | 237,831,737 | |
| -1 | -237,831,737 |
Let's try dividing by 4:
237,831,737 ÷ 4 = 59,457,934.25
If the quotient is a whole number, then 4 and 59,457,934.25 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 | 237,831,737 | |
| -1 | 237,831,737 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 73 | 143 | 803 | 949 | 10,439 | 22,783 | 250,613 | 296,179 | 1,663,159 | 3,257,969 | 18,294,749 | 21,621,067 | 237,831,737 |
| -1 | -11 | -13 | -73 | -143 | -803 | -949 | -10,439 | -22,783 | -250,613 | -296,179 | -1,663,159 | -3,257,969 | -18,294,749 | -21,621,067 | -237,831,737 |
